Laser science or laser physics is a branch of optics that describes the theory and practice of lasers .
92-480: Laser science is principally concerned with quantum electronics , laser construction , optical cavity design, the physics of producing a population inversion in laser media , and the temporal evolution of the light field in the laser. It is also concerned with the physics of laser beam propagation, particularly the physics of Gaussian beams , with laser applications , and with associated fields such as nonlinear optics and quantum optics . Laser science predates
184-711: A cerebral haemorrhage . He was 63 years old. Nobel wrote several wills during his lifetime. He composed the last over a year before he died, signing it at the Swedish–Norwegian Club in Paris on 27 November 1895. To widespread astonishment, Nobel's last will specified that his fortune be used to create a series of prizes for those who confer the "greatest benefit on mankind" in physics , chemistry , physiology or medicine , literature , and peace . Nobel bequeathed 94% of his total assets, 31 million SEK (c. US$ 186 million, €150 million in 2008), to establish
276-434: A population inversion . The use of statistical mechanics is fundamental to the concepts of quantum optics: light is described in terms of field operators for creation and annihilation of photons—i.e. in the language of quantum electrodynamics . A frequently encountered state of the light field is the coherent state , as introduced by E.C. George Sudarshan in 1960. This state, which can be used to approximately describe
368-464: A French newspaper. It was Alfred's brother Ludvig who had died; the obituary was eight years premature. The article disconcerted Nobel and made him apprehensive about how he would be remembered. This inspired him to change his will . Historians have been unable to verify this story and some dismiss the story as a myth. On 10 December 1896, Alfred Nobel died in his villa in San Remo, Italy , from

During the 1890s, von Behring developed an antitoxin to treat diphtheria , which until then had been causing thousands of deaths each year. The first Nobel Peace Prize went to the Swiss Jean Henri Dunant for his role in founding the International Red Cross Movement and initiating
552-402: A consequence of his patent claims, Nobel was eventually involved in a patent infringement lawsuit over cordite. Nobel amassed a fortune during his lifetime, with most of his wealth coming from his 355 inventions, of which dynamite is the most famous. There is a popular story about how, in 1888, Nobel was astonished to read his own obituary , titled "The Merchant of Death Is Dead", in
644-532: A foundation established by Alfred Nobel would reward those who serve humanity. The Nobel Prize was funded by Alfred Nobel's personal fortune. According to the official sources, Alfred Nobel bequeathed most of his fortune to the Nobel Foundation that now forms the economic base of the Nobel Prize. The Nobel Foundation was founded as a private organisation on 29 June 1900. Its function is to manage
736-712: A prize if their impact is realised after the discoverers have died. Except for the Peace Prize, the Nobel Prizes are presented in Stockholm, Sweden, at the annual Prize Award Ceremony on 10 December, the anniversary of Nobel's death. The recipients' lectures are normally held in the days prior to the award ceremony. The Peace Prize and its recipients' lectures are presented at the annual Prize Award Ceremony in Oslo, Norway, usually on 10 December. The award ceremonies and
828-557: A solid funding base for the prizes and the administrative activities. The Nobel Foundation is exempt from all taxes in Sweden (since 1946) and from investment taxes in the United States (since 1953). Since the 1980s, the foundation's investments have become more profitable and as of 31 December 2007, the assets controlled by the Nobel Foundation amounted to 3.628 billion Swedish kronor (c. US$ 560 million). According to
920-415: A whole. However, the subfields of quantum mechanics dealing with matter-light interaction were principally regarded as research into matter rather than into light; hence one rather spoke of atom physics and quantum electronics in 1960. Laser science —i.e., research into principles, design and application of these devices—became an important field, and the quantum mechanics underlying the laser's principles
1012-828: Is 11,000,000 kr , amounting to approximately US$ 1,035,000 . A prize may not be shared among more than three individuals, although the Nobel Peace Prize can be awarded to organisations of more than three people. Nobel Prizes are not awarded posthumously , but if a person is awarded a prize and dies before receiving it, the prize is presented. The Nobel Prizes, beginning in 1901, and the Nobel Memorial Prize in Economic Sciences, beginning in 1969, have been awarded 609 times to 975 people and 25 organisations. Five individuals and two organisations have received more than one Nobel Prize. Alfred Nobel

The Nobel Prizes are widely regarded as the most prestigious awards available in their respective fields. The prize ceremonies take place annually. Each recipient, known as a laureate , receives a green gold medal plated with 24 karat gold, a diploma , and a monetary award. As of 2023, the Nobel Prize monetary award
1196-414: Is announced immediately after the vote. A maximum of three laureates and two different works may be selected per award. Except for the Peace Prize, which can be awarded to institutions, the awards can only be given to individuals. The winners are announced by the awarding institutions during the first two weeks of October. Although posthumous nominations are not presently permitted, individuals who died in
1288-412: Is associated with a photon in the other beam. Atoms are considered as quantum mechanical oscillators with a discrete energy spectrum , with the transitions between the energy eigenstates being driven by the absorption or emission of light according to Einstein's theory. For solid state matter, one uses the energy band models of solid state physics . This is important for understanding how light
1380-497: Is detected by solid-state devices, commonly used in experiments. Quantum electronics is a term that was used mainly between the 1950s and 1970s to denote the area of physics dealing with the effects of quantum mechanics on the behavior of electrons in matter, together with their interactions with photons . Today, it is rarely considered a sub-field in its own right, and it has been absorbed by other fields. Solid state physics regularly takes quantum mechanics into account, and
1472-582: Is similar for all of the Nobel Prizes, the main difference being who can make nominations for each of them. Nomination forms are sent by the Nobel Committee to about 3,000 individuals, usually in September the year before the prizes are awarded. These individuals are generally prominent academics working in a relevant area. Regarding the Peace Prize, inquiries are also sent to governments, former Peace Prize laureates, and current or former members of
1564-630: Is usually concerned with electrons. Specific applications of quantum mechanics in electronics is researched within semiconductor physics . The term also encompassed the basic processes of laser operation, which is today studied as a topic in quantum optics. Usage of the term overlapped early work on the quantum Hall effect and quantum cellular automata .

1656-715: The Economic Sciences prize of 16.5 Million kronor is paid by the Sveriges Riksbank . Once the Nobel Foundation and its guidelines were in place, the Nobel Committees began collecting nominations for the inaugural prizes. Subsequently, they sent a list of preliminary candidates to the prize-awarding institutions. The Nobel Committee's Physics Prize shortlist cited Wilhelm Röntgen 's discovery of X-rays and Philipp Lenard 's work on cathode rays . The Academy of Sciences selected Röntgen for
1748-823: The Rohingya genocide and calls were made to strip her of her Nobel Peace Prize. The award of the 2004 Literature Prize to Elfriede Jelinek drew a protest from a member of the Swedish Academy, Knut Ahnlund . Ahnlund resigned, alleging that the selection of Jelinek had caused "irreparable damage to all progressive forces, it has also confused the general view of literature as an art". He alleged that Jelinek's works were "a mass of text shovelled together without artistic structure". The 2009 Literature Prize to Herta Müller also generated criticism. According to The Washington Post , many US literary critics and professors were ignorant of her work. This made those critics feel
1840-476: The electromagnetic fields describing the waves in the classical picture. In 1977, Kimble et al. demonstrated a single atom emitting one photon at a time, further compelling evidence that light consists of photons. Previously unknown quantum states of light with characteristics unlike classical states, such as squeezed light were subsequently discovered. Development of short and ultrashort laser pulses—created by Q switching and modelocking techniques—opened
1932-453: The speed of light in vacuum. These particles should not be considered to be classical billiard balls , but as quantum mechanical particles described by a wavefunction spread over a finite region. Each particle carries one quantum of energy, equal to hf , where h is the Planck constant and f is the frequency of the light. That energy possessed by a single photon corresponds exactly to

#17327985308962024-628: The trustees . However, since 1995, all the members of the board have been chosen by the trustees, and the executive director and the deputy director appointed by the board itself. As well as the board, the Nobel Foundation is made up of the prize-awarding institutions (the Royal Swedish Academy of Sciences, the Nobel Assembly at Karolinska Institute, the Swedish Academy, and the Norwegian Nobel Committee ),
2116-551: The 1926 Prize in Physiology or Medicine for his purported discovery of a parasite that caused cancer. To avoid repeating this embarrassment, the awards increasingly recognised scientific discoveries that had withstood the test of time. According to Ralf Pettersson, former chairman of the Nobel Prize Committee for Physiology or Medicine, "the criterion 'the previous year' is interpreted by the Nobel Assembly as
2208-420: The 1980s, when the prize money was 880,000 SEK per prize (c. 2.6 million SEK altogether, US$ 350,000 today). In 2009, the monetary award was 10 million SEK (US$ 1.4 million). In June 2012, it was lowered to 8 million SEK. If two laureates share the prize in a category, the award grant is divided equally between the recipients. If there are three, the awarding committee has the option of dividing
2300-512: The 2022 Chemistry Prize for click chemistry . Two organisations have received the Peace Prize multiple times. The International Committee of the Red Cross received it three times: in 1917 and 1944 for its work during the world wars; and in 1963 during the year of its centenary. The United Nations High Commissioner for Refugees has been awarded the Peace Prize twice for assisting refugees: in 1954 and 1981. The Curie family has received
2392-586: The Geneva Convention, and jointly given to French pacifist Frédéric Passy , founder of the Peace League and active with Dunant in the Alliance for Order and Civilization. In 1938 and 1939, Adolf Hitler 's Third Reich forbade three laureates from Germany ( Richard Kuhn , Adolf Friedrich Johann Butenandt , and Gerhard Domagk ) from accepting their prizes. They were all later able to receive
2484-475: The King and Queen of Norway. In total, about 250 guests attend. According to the statutes of the Nobel Foundation, each laureate is required to give a public lecture on a subject related to the topic of their prize. The Nobel lecture as a rhetorical genre took decades to reach its current format. These lectures normally occur during Nobel Week (the week leading up to the award ceremony and banquet, which begins with
2576-526: The Mint of Norway, located in Kongsberg, made the medals. The Nobel Prize medals are registered trademarks of the Nobel Foundation. Each medal features an image of Alfred Nobel in left profile on the obverse . The medals for physics, chemistry, physiology or medicine, and literature have identical obverses, showing the image of Alfred Nobel and the years of his birth and death. Nobel's portrait also appears on
2668-435: The Nobel Peace Prize." Yasser Arafat , Shimon Peres , and Yitzhak Rabin received the Peace Prize in 1994 for their efforts in making peace between Israel and Palestine. Immediately after the award was announced, one of the five Norwegian Nobel Committee members denounced Arafat as a terrorist and resigned. Additional misgivings about Arafat were widely expressed in various newspapers. Another controversial Peace Prize
2760-668: The Nobel Prize Award Ceremony in Stockholm occurs when each Nobel laureate steps forward to receive the prize from the hands of the King of Sweden . In Oslo, the chairman of the Norwegian Nobel Committee presents the Nobel Peace Prize in the presence of the King of Norway and the Norwegian royal family . At first, King Oscar II did not approve of awarding grand prizes to foreigners. After

Those hostile to the North and what they considered its deceptive practices during negotiations were deprived of a chance to criticise Lê Đức Thọ, as he declined the award. The satirist and musician Tom Lehrer has remarked that "political satire became obsolete when Henry Kissinger was awarded
3036-516: The Norwegian Nobel Committee fled into exile. The remaining members escaped persecution from the Germans when the Nobel Foundation stated that the committee building in Oslo was Swedish property. Thus it was a safe haven from the German military, which was not at war with Sweden. These members kept the work of the committee going, but did not award any prizes. In 1944, the Nobel Foundation, together with

The Nobel Committee nominates about 300 potential laureates from these forms and additional names. The nominees are not publicly named, nor are they told that they are being considered for the prize. All nomination records for a prize are sealed for 50 years from the awarding of
3220-602: The Physiology or Medicine Prize for his development of the prefrontal leucotomy . The previous year, Walter Freeman had developed a version of the procedure which was faster and easier to carry out. Due in part to the publicity surrounding the original procedure, Freeman's procedure was prescribed without due consideration or regard for modern medical ethics . Endorsed by such influential publications as The New England Journal of Medicine , leucotomy or "lobotomy" became so popular that about 5,000 lobotomies were performed in
3312-600: The Physiology or Medicine Prize in 1959; Kornberg's son Roger later received the Chemistry Prize in 2006. Arthur Schawlow received the 1981 Physics prize, and was married to the sister of 1964 Physics laureate Charles Townes . Two members of the Hodgkin family received Nobels in consecutive years: Sir Alan Lloyd Hodgkin shared in the Nobel for Physiology or Medicine in 1963, followed by Dorothy Crowfoot Hodgkin ,
3404-646: The associated banquets are typically major international events. The Prizes awarded in Sweden's ceremonies are held at the Stockholm Concert Hall , with the Nobel banquet following immediately at Stockholm City Hall . The Nobel Peace Prize ceremony has been held at the Norwegian Nobel Institute (1905–1946), at the auditorium of the University of Oslo (1947–1989), and at Oslo City Hall (1990–present). The highlight of

Obama's award, along with the previous Peace Prizes for Jimmy Carter and Al Gore , also prompted accusations of a liberal bias. Aung San Suu Kyi was awarded Peace Prize in 1993 however in 2015 when she came into power in Myanmar , she was criticized for being silent on human rights violation under her rule and especially over
3680-409: The decision to award Steinman the prize "was made in good faith", it would remain unchanged, and the prize would be awarded. Nobel's will provided for prizes to be awarded in recognition of discoveries made "during the preceding year". Early on, the awards usually recognised recent discoveries. However, some of those early discoveries were later discredited. For example, Johannes Fibiger was awarded
3772-471: The decisive factor that enabled the Nobel Prizes to be established". Another important task of the Nobel Foundation is to market the prizes internationally and to oversee informal administration related to the prizes. The foundation is not involved in the process of selecting the Nobel laureates . In many ways, the Nobel Foundation is similar to an investment company , in that it invests Nobel's money to create

3864-482: The diploma and medal. Even though Sweden was officially neutral during the Second World War, the prizes were awarded irregularly. In 1939, the Peace Prize was not awarded. No prize was awarded in any category from 1940 to 1942, due to the occupation of Norway by Germany . In the subsequent year, all prizes were awarded except those for literature and peace. During the occupation of Norway, three members of

Robert and Ludvig Nobel were involved in the oil business in Azerbaijan , and according to Swedish historian E. Bargengren, who accessed the Nobel family archive , it was this "decision to allow withdrawal of Alfred's money from Baku that became
4232-555: The five Nobel Prizes. Owing to skepticism surrounding the will, it was not approved by the Storting in Norway until 26 April 1897. The executors of the will, Ragnar Sohlman and Rudolf Lilljequist, formed the Nobel Foundation to take care of the fortune and to organise the awarding of prizes. Nobel's instructions named a Norwegian Nobel Committee to award the Peace Prize , the members of which were appointed shortly after
4324-477: The grant equally, or awarding one-half to one recipient and one-quarter to each of the others. It is common for recipients to donate prize money to benefit scientific, cultural, or humanitarian causes. Five people have received two Nobel Prizes. Marie Curie received the Physics Prize in 1903 for her work on radioactivity and the Chemistry Prize in 1911 for the isolation of pure radium , making her
4416-426: The holders. After the war, the gold was recovered from solution, and the medals re-cast. Nobel laureates receive a diploma directly from the hands of the King of Sweden, or in the case of the peace prize, the chairman of the Norwegian Nobel Committee. Each diploma is uniquely designed by the prize-awarding institutions for the laureates that receive them. The diploma contains a picture and text in Swedish which states
4508-514: The invention of the transistor and in 1972 for the theory of superconductivity . Frederick Sanger received the prize twice in Chemistry: in 1958 for determining the structure of the insulin molecule and in 1980 for inventing a method of determining base sequences in DNA. Karl Barry Sharpless was awarded the 2001 Chemistry Prize for his research into chirally catalysed oxidation reactions, and
4600-479: The invention of the laser itself. Albert Einstein created the foundations for the laser and maser in 1917, via a paper in which he re-derived Max Planck ’s law of radiation using a formalism based on probability coefficients ( Einstein coefficients ) for the absorption , spontaneous emission , and stimulated emission of electromagnetic radiation. The existence of stimulated emission was confirmed in 1928 by Rudolf W. Ladenburg . In 1939, Valentin A. Fabrikant made

This has occurred twice: the 1931 Literature Prize awarded to Erik Axel Karlfeldt , and the 1961 Peace Prize awarded to UN Secretary General Dag Hammarskjöld . Since 1974, laureates must be thought alive at the time of the October announcement. There has been one laureate, William Vickrey , who in 1996 died after
4968-549: The most criticised Nobel Peace Prizes was the one awarded to Henry Kissinger and Lê Đức Thọ . This led to the resignation of two Norwegian Nobel Committee members. Kissinger and Thọ were awarded the prize for negotiating a ceasefire between North Vietnam and the United States in January 1973 during the Vietnam War . However, when the award was announced, both sides were still engaging in hostilities. Critics sympathetic to

Her husband, Pierre Curie , shared the 1903 Physics prize with her. Their daughter, Irène Joliot-Curie , received the Chemistry Prize in 1935 together with her husband Frédéric Joliot-Curie . In addition, the husband of Marie Curie's second daughter, Henry Labouisse ,
5152-422: The name of the laureate and normally a citation of why they received the prize. None of the Nobel Peace Prize laureates has ever had a citation on their diplomas. The laureates are given a sum of money when they receive their prizes, in the form of a document confirming the amount awarded. The amount of prize money depends upon how much money the Nobel Foundation can award each year. The purse has increased since

The first major development leading to that understanding was the correct modeling of the blackbody radiation spectrum by Max Planck in 1899 under the hypothesis of light being emitted in discrete units of energy. The photoelectric effect was further evidence of this quantization as explained by Albert Einstein in a 1905 paper, a discovery for which he

For instance, the laureate's name is engraved on the rim of the Economics medal. The image on the reverse of a medal varies according to the institution awarding the prize. The reverse sides of the medals for chemistry and physics share the same design. All medals made before 1980 were struck in 23 carat gold. Since then, they have been struck in 18 carat green gold plated with 24 carat gold. The weight of each medal varies with

Linus Pauling was awarded the 1954 Chemistry Prize for his research into the chemical bond and its application to the structure of complex substances. Pauling was also awarded the Peace Prize in 1962 for his activism against nuclear weapons, making him the only laureate of two unshared prizes. John Bardeen received the Physics Prize twice: in 1956 for

The first maser was built by Charles H. Townes , James P. Gordon , and Herbert J. Zeiger in 1953. Townes, Basov and Prokhorov were awarded the Nobel Prize in Physics in 1964 for their research in the field of stimulated emission. Arthur Ashkin , Gérard Mourou , and Donna Strickland were awarded
5612-602: The output of a single-frequency laser well above the laser threshold, exhibits Poissonian photon number statistics. Via certain nonlinear interactions, a coherent state can be transformed into a squeezed coherent state , by applying a squeezing operator that can exhibit super - or sub-Poissonian photon statistics. Such light is called squeezed light . Other important quantum aspects are related to correlations of photon statistics between different beams. For example, spontaneous parametric down-conversion can generate so-called 'twin beams', where (ideally) each photon of one beam

A group including 42 Swedish writers, artists, and literary critics protested against this decision, having expected Leo Tolstoy to be awarded. Some, including Burton Feldman , have criticised this prize because they consider Prudhomme a mediocre poet. Feldman's explanation is that most of the academy members preferred Victorian literature and thus selected

Photons have been used to test many of the counter-intuitive predictions of quantum mechanics , such as entanglement and teleportation , and are a useful resource for quantum information processing . Light propagating in a restricted volume of space has its energy and momentum quantized according to an integer number of particles known as photons . Quantum optics studies
6440-410: The term of quantum optics, especially as applied to engineering and technological innovation, often go under the modern term photonics . Several Nobel prizes have been awarded for work in quantum optics. These were awarded: According to quantum theory , light may be considered not only to be as an electro-magnetic wave but also as a "stream" of particles called photons , which travel with c ,

The diameter is 66 millimetres (2.6 in) and the thickness varies between 5.2 millimetres (0.20 in) and 2.4 millimetres (0.094 in). Because of the high value of their gold content and tendency to be on public display, Nobel medals are subject to medal theft. During World War II, the medals of German scientists Max von Laue and James Franck were sent to Copenhagen for safekeeping. When Germany invaded Denmark, Hungarian chemist (and Nobel laureate himself) George de Hevesy dissolved them in aqua regia (nitro-hydrochloric acid), to prevent confiscation by Nazi Germany and to prevent legal problems for
6992-409: The way to the study of what became known as ultrafast processes. Applications for solid state research (e.g. Raman spectroscopy ) were found, and mechanical forces of light on matter were studied. The latter led to levitating and positioning clouds of atoms or even small biological samples in an optical trap or optical tweezers by laser beam. This, along with Doppler cooling and Sisyphus cooling ,
7084-476: The wife of his first cousin, who won solo for Chemistry in 1964. Jan Tinbergen , who was awarded the first Economics Prize in 1969, was the brother of Nikolaas Tinbergen , who received the 1973 Physiology or Medicine Prize. Gunnar Myrdal , who was awarded the Economics Prize in 1974, was the husband of Alva Myrdal , Peace Prize laureate in 1982. Economics laureates Paul Samuelson (1970) and Kenneth Arrow (1972; shared) were brothers-in-law. Frits Zernike , who
7176-712: The will was approved in April 1897. Soon thereafter, the other prize-awarding organisations were designated. These were the Karolinska Institute on 7 June, the Swedish Academy on 9 June, and the Royal Swedish Academy of Sciences on 11 June. The Nobel Foundation reached an agreement on guidelines for how the prizes should be awarded; and, in 1900, the Nobel Foundation's newly created statutes were promulgated by King Oscar II . According to his will and testament read in Stockholm on 30 December 1896,
7268-412: The year when the full impact of the discovery has become evident." The interval between the award and the accomplishment it recognises varies from discipline to discipline. The Literature Prize is typically awarded to recognise a cumulative lifetime body of work rather than a single achievement. The Peace Prize can also be awarded for a lifetime body of work. For example, 2008 laureate Martti Ahtisaari
7360-625: Was awarded for his work to resolve international conflicts. However, they can also be awarded for specific recent events. For instance, Kofi Annan was awarded the 2001 Peace Prize just four years after becoming the Secretary-General of the United Nations. Similarly Yasser Arafat , Yitzhak Rabin , and Shimon Peres received the 1994 award, about a year after they successfully concluded the Oslo Accords . A controversy
7452-417: Was awarded for the first time. The Royal Swedish Academy of Sciences became responsible for selecting laureates. The first laureates for the Economics Prize were Jan Tinbergen and Ragnar Frisch "for having developed and applied dynamic models for the analysis of economic processes". The board of the Nobel Foundation decided that after this addition, it would allow no further new prizes. The award process
7544-557: Was awarded the 1953 Physics Prize, was the great-uncle of 1999 Physics laureate Gerard 't Hooft . In 2019, married couple Abhijit Banerjee and Esther Duflo were awarded the Economics Prize. Christiane Nüsslein-Volhard was awarded the Prize in Physiology or Medicine in 1995, and her nephew Benjamin List received the Chemistry Prize in 2021. Sune Bergström was awarded the Prize in Physiology or Medicine in 1982, and his son Svante Pääbo
7636-655: Was awarded the same prize in 2022. Edwin McMillan , who shared the Prize in Chemistry in 1951, was the uncle of John Clauser , who was awarded the Prize in Physics in 2022. Among other criticisms, the Nobel Committees have been accused of having a political agenda, and of omitting more deserving candidates. They have also been accused of Eurocentrism , especially for the Literature Prize. Among
7728-422: Was awarded to Manne Siegbahn in 1924, followed by his son, Kai Siegbahn , in 1981. Hans von Euler-Chelpin , who received the Chemistry Prize in 1929, was the father of Ulf von Euler , who was awarded the Physiology or Medicine Prize in 1970. C. V. Raman was awarded the Physics Prize in 1930 and was the uncle of Subrahmanyan Chandrasekhar , who was awarded the same prize in 1983. Arthur Kornberg received
7820-563: Was born on 21 October 1833 in Stockholm , Sweden, into a family of engineers. He was a chemist , engineer , and inventor . In 1894, Nobel purchased the Bofors iron and steel mill, which he made into a major armaments manufacturer . Nobel also invented ballistite . This invention was a precursor to many smokeless military explosives, especially the British smokeless powder cordite . As
7912-498: Was caused by awarding the 2009 Nobel Peace Prize to Barack Obama during his first year as US president. Awards for physics, chemistry, and medicine are typically awarded once the achievement has been widely accepted. Sometimes, this takes decades – for example, Subrahmanyan Chandrasekhar shared the 1983 Physics Prize for his 1930s work on stellar structure and evolution. Not all scientists live long enough for their work to be recognised. Some discoveries can never be considered for
8004-425: Was studied now with more emphasis on the properties of light , and the name quantum optics became customary. As laser science needed good theoretical foundations, and also because research into these soon proved very fruitful, interest in quantum optics rose. Following the work of Dirac in quantum field theory , John R. Klauder , George Sudarshan , Roy J. Glauber , and Leonard Mandel applied quantum theory to
8096-406: Was that awarded to Barack Obama in 2009 . Nominations had closed only eleven days after Obama took office as President of the United States , but the actual evaluation occurred over the next eight months. Obama himself stated that he did not feel deserving of the award, or worthy of the company in which it would place him. Past Peace Prize laureates were divided, some saying that Obama deserved
8188-809: Was the crucial technology needed to achieve the celebrated Bose–Einstein condensation . Other remarkable results are the demonstration of quantum entanglement , quantum teleportation , and quantum logic gates . The latter are of much interest in quantum information theory , a subject that partly emerged from quantum optics, partly from theoretical computer science . Today's fields of interest among quantum optics researchers include parametric down-conversion , parametric oscillation , even shorter (attosecond) light pulses, use of quantum optics for quantum information , manipulation of single atoms, Bose–Einstein condensates , their application, and how to manipulate them (a sub-field often called atom optics ), coherent perfect absorbers , and much more. Topics classified under
8280-531: Was the director of UNICEF when he accepted the Nobel Peace Prize in 1965 on that organisation's behalf. Although no family matches the Curie family's record, there have been several with two laureates. The Nobel Prize in Physiology or Medicine was awarded to the husband-and-wife team of Gerty Cori and Carl Ferdinand Cori in 1947, and to the husband-and-wife team of May-Britt Moser and Edvard Moser in 2014 (along with John O'Keefe ). The Physics Prize in 1906
8372-416: Was to be awarded the Nobel Prize in 1921. Niels Bohr showed that the hypothesis of optical radiation being quantized corresponded to his theory of the quantized energy levels of atoms , and the spectrum of discharge emission from hydrogen in particular. The understanding of the interaction between light and matter following these developments was crucial for the development of quantum mechanics as
8464-423: Was won by J. J. Thomson for showing that electrons are particles, and in 1937 by his son, George Paget Thomson , for showing that they also have the properties of waves . William Henry Bragg and his son, William Lawrence Bragg , shared the Physics Prize in 1915 for inventing X-ray crystallography . Niels Bohr was awarded the Physics Prize in 1922, as was his son, Aage Bohr , in 1975. The Physics Prize
