Paul Corkum
Paul Bruce Corkum ( born October 30, 1943 in Saint John (New Brunswick ) ) is a Canadian physicist who deals with laser physics and atomic physics and a pioneer of atomic and molecular physics in the time ranges of attosecond is with the use of appropriate ultrashort laser pulses. He is director of the Laboratory for Photonics Attoseconds the University of Ottawa - National Research Council of Canada.
Life
Corkum received a Bachelor of Science degree in 1965 at Acadia University in Nova Scotia. In 1967 he received the Master of Science and Ph.D. 1972 in theoretical physics at Lehigh University, Pennsylvania. He remained as a post- graduate student for one year at Lehigh University, and went in 1973 to the National Research Council of Canada (NRC ) and moved there from the theoretical to the experimental physics. According to his own statements, he convinced himself and his future employer by the fact that he had previously learned during their studies to repair cars from scratch. In 1990 he formed the Steacie Institute for Molecular Science of the NRC a femtosecond research group, which was under his leadership to a world-leading research groups in this field. In 2008 he became a professor ( on a Canada Research Chair ) for Attosecond Photonics at the University of Ottawa and Director of the Joint Laboratory of NRC and University of Ottawa for Research in the attosecond range. He is also Adjunct Professor at McMaster University, the University of British Columbia and Texas A & M University.
Corkum works both theoretically and experimentally. In the 1980s, he developed a model of the ionization of atoms and thus developed a new proposal for X-ray lasers (Optical field ionization OFI ). In the 1990s, he developed theories about different atomic physical phenomena in strong fields, such as the generation of higher harmonics and correlated double ionization. His re -collision electron model in which is carried out by an intense laser field tunneling ionization, the tunneled electron but then returned accelerated in the laser field on the ion and there correlated with the bound state superimposed, served as the basis for suggesting the generation of attosecond pulses, of him with Austrian colleagues first time in 2001 succeeded (pulse length less than 1 femtosecond ). It was used for the generation of higher harmonics and (as a type of laser tunneling microscope ) for exploration of atoms and molecules in the angstrom range and below.
Corkum has received numerous awards for his work in the field of lasers.
