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 Fr ... [...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 a graduate school of 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 demonstration of the existence of the ozone layer in the atmosphere. On October 21, 1916, Gramont had lunch with four government ministers. As a result, a new committee was formed, in ... [...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. A femtosecond is to a second, as a second is to approximately 31.69 million years. For context, 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: The first to make femtosecond measurements was the Egyptian Nobel Laureate Ahmed Zewail, for which he was awarded the Nobel Prize in Chemistry in 1999. Professor Zewail used lasers to measure the movement of particles at the femtosecond scale, thereby allowing chemical reactions to be observed for the first time. 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 10â ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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'' originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow and the optical amplifier patented by Gordon Gould. A laser differs from other sources of light in that it emits light that is coherence (physics), ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling uses such as optical communication, laser cutting, and Photolithography#Light sources, lithography. It also allows a laser beam to stay narrow over great distances (collimated light, collimation), used in laser pointers, lidar, and free-space optical communication. Lasers can also have high temporal coherence, which permits them to emit light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 cooperation ...

Quantum State
In quantum physics, a quantum state is a mathematical entity that embodies the knowledge of a quantum system. Quantum mechanics specifies the construction, evolution, and measurement of a quantum state. The result is a prediction for the system represented by the state. Knowledge of the quantum state, and the rules for the system's evolution in time, exhausts all that can be known about a quantum system. Quantum states may be defined differently for different kinds of systems or problems. Two broad categories are * wave functions describing quantum systems using position or momentum variables and * the more abstract vector quantum states. Historical, educational, and application-focused problems typically feature wave functions; modern professional physics uses the abstract vector states. In both categories, quantum states divide into pure versus mixed states, or into coherent states and incoherent states. Categories with special properties include stationary states for tim ...
