Béatrice Chatel
Béatrice Chatel is a French physicist and researcher specializing in femtosecond lasers. She was awarded an Irène Joliot-Curie Prize in 2005 for her work. Life and work In 1993, Chatel graduated from the Institut d'optique Graduate School, sometimes called "SupOptique." She completed her thesis at the Kastler Brossel laboratory and then became a lecturer at the University Toulouse-III-Paul-Sabatier. After a short period at the Applied Optics Laboratory, she began full time research at the Collisions, Aggregates, Reactivity (LCAR) laboratory as a research fellow. Between 2013 and 2014, she was director of the laboratory. Chatel distinguished herself by developing a laser capable of shaping its pulses in an extremely precise way. Using this tool, researchers can break up molecules in a controlled manner depending on the properties of the laser pulse to which they are subjected. In addition to her work as a researcher, Chatel was president of the steering committee of the Fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
École Supérieure D'optique
The Institut d'optique Graduate School ("Institute of optics"), nicknamed SupOptique or IOGS, is one of the most prestigious French Grandes Ecoles and the leading French ''grande école'' in the field of Optics and its industrial and scientific applications, and a graduate school of the prestigious Paris-Saclay University and ParisTech. History Armand de Gramont, a rich industrialist and friend of Marcel Proust, was the man who had the idea to create the Institut d'Optique. In 1916, Gramont and Henri Chrétien (a French astronomer) were working together at the French Technical Aeronautics Section. Chrétien was working at the time on calculations for optical instruments. They both decided to create the project of building an institute dedicated to teaching Optics. That same year, Gramont became part of a committee that examined inventions that could interest the ministry of Defense. That is where he met Charles Fabry, who had previously become famous thanks to his experimental ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Femtosecond
A femtosecond is a unit of time in the International System of Units (SI) equal to 10 or of a second; that is, one quadrillionth, or one millionth of one billionth, of a second. For context, a femtosecond is to a second as a second is to about 31.71 million years; a ray of light travels approximately 0.3 μm (micrometers) in 1 femtosecond, a distance comparable to the diameter of a virus.Compared with overview in: Page 3 The word ''femtosecond'' is formed by the SI prefix ''femto'' and the SI unit ''second''. Its symbol is fs. A femtosecond is equal to 1000 attoseconds, or 1/1000 picosecond. Because the next higher SI unit is 1000 times larger, times of 10−14 and 10−13 seconds are typically expressed as tens or hundreds of femtoseconds. * Typical time steps for molecular dynamics simulations are on the order of 1 fs. * The periods of the waves of visible light have a duration of about 2 femtoseconds. = = 2.0 \times 10^~ The precise duration depends on the ener ...

Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of ligh ...

Kastler–Brossel Laboratory
The Kastler–Brossel Laboratory, (formerly the Laboratory of Hertzian Spectroscopy) located in Paris, France, is a research laboratory specializing in fundamental physics of quantum systems. Founded in 1951 by Alfred Kastler and Jean Brossel, it is a joint research unit ( French UMR 8552) operated by the French National Centre for Scientific Research (CNRS), the École normale supérieure, the Sorbonne University and the Collège de France. Brief history The laboratory was founded in 1951 by Alfred Kastler (Nobel Prize in Physics in 1966) and Jean Brossel on the theme of the interaction between light and matter. The initial name of laboratory was the « Laboratoire de spectroscopie Hertzienne de l'ENS » (Laboratory of Hertzian Spectroscopy). It is located in the Department of Physics of École normale supérieure. In 1967, a second site opened on the Jussieu campus. In 1994, the laboratory changed its name to « Laboratoire Kastler Brossel » in honor of its two founders. No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toulouse III - Paul Sabatier University
Paul Sabatier University (''Université Paul Sabatier'', UPS, also known as Toulouse III) is a French public university, in the Academy of Toulouse. It is one of the several successor universities of the University of Toulouse. Toulouse III was named after Paul Sabatier, winner of the 1912 Nobel prize in chemistry.

World Year Of Physics 2005
The year 2005 was named the World Year of Physics, also known as Einstein Year, in recognition of the 100th anniversary of Albert Einstein's " Miracle Year", in which he published four landmark papers, and the subsequent advances in the field of physics. History Physics has been the basis for understanding the physical world and nature as a whole. The applications of physics are the basis for much of today's technology. In order to both raise worldwide awareness of physics and celebrate the major advances made in the field, the World Congress of Physical Societies proposed and the International Union of Pure and Applied Physics resolved that 2005 should be commemorated as the World Year of Physics. This was subsequently endorsed by UNESCO. Selected celebrations The World Year of Physics officially began with a conference held in mid-January in Paris, titled ''Physics for Tomorrow''. * In the United States, the University of Maryland sponsored several activities in cooperatio ...

Irène Joliot-Curie Prize
The Irène Joliot-Curie Prize is a French prize for women in science and technology, founded in 2001. It is awarded by the Ministry of Higher Education, Research and Innovation, the Airbus Group corporate foundation, the French Academy of Sciences and the Academy of Technologies, it aims at rewarding women for their work in the fields of science and technology". The prize is named after French scientist Irène Joliot-Curie, a French chemist, physicist and politician who won the Nobel Prize in Chemistry in 1935 for the discovery of artificial radioactivity. (This prize should be distinguished from a different prize with the same name, offered since 1956 by the Société Française de Physique. which rewards work in the field of physics each year.) Each year three awards are given: one for the female scientist of the year, a second to a young female scientist, and a third to a woman in business and technology. In addition, until 2009, of the award a fourth category of awards was g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
21st-century French Physicists
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius ( AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman em ...
