Gérard Mourou
Gérard Albert Mourou (; born 22 June 1944) is a French scientist and pioneer in the field of electrical engineering and lasers. He was awarded a Nobel Prize in Physics in 2018, along with Donna Strickland, for the invention of chirped pulse amplification, a technique later used to create ultrashort-pulse, very high-intensity (petawatt) laser pulses. In 1994, Mourou and his team at the University of Michigan discovered that the balance between the self-focusing refraction (see Kerr effect) and self-attenuating diffraction by ionization and rarefaction of a laser beam of terawatt intensities in the atmosphere creates "filaments" that act as waveguides for the beam, thus preventing divergence. Career Mourou has been director of the Laboratoire d'optique appliquée at the ENSTA from 2005 to 2009. He is a professor and member of Haut Collège at the École polytechnique and A. D. Moore Distinguished University Professor Emeritus at the University of Michigan where he has taught fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Université Grenoble Alpes
The Université Grenoble Alpes (UGA, French: meaning "''Grenoble Alps University''") is a public research university in Grenoble, France. Founded in 1339, it is the third largest university in France with about 60,000 students and over 3,000 researchers. Established as the University of Grenoble by Humbert II of Viennois, it split in 1970 following the wide-spread civil unrest of May 1968. Three of the University of Grenoble's successors—Joseph Fourier University, Pierre Mendès-France University, and Stendhal University—merged in 2016 to restore the original institution under the name Université Grenoble Alpes. In 2020, the Grenoble Institute of Technology, the Grenoble Institute of Political Studies, and the Grenoble School of Architecture also merged with the original university. The university is organized around two closely located urban campuses: Domaine Universitaire, which straddles Saint-Martin-d'Hères and Gières, and Campus GIANT in Grenoble. UGA also owns and ope ...

Donna Strickland
Donna Theo Strickland (born 27 May 1959) is a Canadian optical physicist and pioneer in the field of pulsed lasers. She was awarded the Nobel Prize in Physics in 2018, together with Gérard Mourou, for the practical implementation of chirped pulse amplification. She is a professor at the University of Waterloo in Ontario, Canada. She served as fellow, vice president, and president of Optica (formerly OSA), and is currently chair of its Presidential Advisory Committee. In 2018, she was listed as one of BBC's 100 Women. Early life and education Strickland was born on 27 May 1959, in Guelph, Ontario, Canada to Edith J. (), an English teacher, and Lloyd Strickland, an electrical engineer. After graduating from Guelph Collegiate Vocational Institute, she decided to attend McMaster University because its engineering physics program included lasers and electro-optics, areas of particular interest to her. At McMaster, she was one of three women in a class of twenty-five. Strickland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Petawatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : \mathr ...

The Guardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. Since 2018, the paper's main news ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gérard Mourou EM1B5793 (46234161551)
Gérard (French: ) is a French masculine given name and surname of Germanic origin, variations of which exist in many Germanic and Romance languages. Like many other early Germanic names, it is dithematic, consisting of two meaningful constituents put together. In this case, those constituents are ''gari'' > ''ger-'' (meaning 'spear') and -''hard'' (meaning 'hard/strong/brave'). The English cognate of Gérard is Gerard.

Arthur Ashkin
Arthur Ashkin (September 2, 1922 – September 21, 2020) was an American scientist and Nobel laureate who worked at Bell Laboratories and Lucent Technologies. Ashkin has been considered by many as the father of optical tweezers, "LaserFest – the 50th anniversary of the first laser" for which he was awarded the Nobel Prize in Physics 2018 at age 96, becoming the oldest Nobel Laureate until 2019 when John B. Goodenough was awarded at 97. He resided in Rumson, New Jersey. Ashkin started his work on manipulation of microparticles with laser light in the late 1960s which resulted in the invention of optical tweezers in 1986. He also pioneered the optical trapping process that eventually was used to manipulate atoms, molecules, and biological cells. The key phenomenon is the radiation pressure of light; this pressure can be dissected down into optical gradient and scattering forces. Early life and family Arthur Ashkin was born in Brooklyn, New York, in 1922, to a family of Ukraini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extreme Light Infrastructure
The Extreme Light Infrastructure (ELI) is an international series of physics laboratories for generating and studying intense laser light. It is part of the European ESFRI Roadmap. ELI hosts the most intense beamline system worldwide, develop new interdisciplinary research opportunities with light from these lasers and secondary radiation derived from them, and make them available to the international scientific user community. ELI aims to be the world's biggest and first international user facility in beamline and laser research. The facility will be based on four sites. Three of them are presently being implemented in the Czech Republic, Hungary and Romania, with an investment volume exceeding €850 million, mostly stemming from the European Regional Development Fund (ERDF). In Dolní Břežany, near Prague, Czech Republic, the ELI Beamlines facility is developing short-pulse secondary sources of radiation and particles.

Laboratory For Laser Energetics
The Laboratory for Laser Energetics (LLE) is a scientific research facility which is part of the University of Rochester's south campus, located in Brighton, New York. The lab was established in 1970 and its operations since then have been funded jointly; mainly by the United States Department of Energy, the University of Rochester and the New York State government. The Laser Lab was commissioned to serve as a center for investigations of high-energy physics, specifically those involving the interaction of extremely intense laser radiation with matter. Many types of scientific experiments are performed at the facility with a strong emphasis on inertial confinement, direct drive, laser-induced fusion, fundamental plasma physics and astrophysics using the Omega Laser Facility. In June 1995, OMEGA became the world's highest-energy ultraviolet laser."World's Most Powerful Ultraviolet Laser Comes On-line" http://www.rochester.edu/news/show.php?id=641 The lab shares its building with t ...
