Biography

Dr. Paul Corkum, he obtained his BSc (1965) from Acadia University, Nova Scotia, and his MSc (1967) and PhD (1972) in theoretical physics from Lehigh University, Pennsylvania.

Dr. Paul Corkum is a Canadian physicist specializing in attosecond physics and laser science. He is now the professor of physics at University of Ottawa, also, he is the director of NRC (National Research Council) Attosecond Science Program. He holds a joint University of Ottawa–NRC chair in Attosecond Photonics. He is one of the students of strong field atomic physics, i.e. atoms and plasmas in super-intense laser fields. He won several awards for his work on laser science.

Dr. Paul Corkum is both a theorist and an experimentalist. In the 1980s he developed a model of the ionization of atoms (i.e. plasma production) and on this basis proposed a new approach to making X-ray lasers (Optical field Ionization, OFI). OFI lasers are today one of the most important developments in X-ray laser research. In the early 1990s in strong field atomic physics there were discoveries of high harmonic generation and correlated double ionization (in which an atom can absorb hundreds of photons and emit two electrons). His Recollision Electron Model served as the basis for the generation of attosecond pulses from lasers. With this method in 2001 he with colleagues in Vienna succeeded in demonstrating for the first time laser pulse lengths lasting less than 1 femtosecond. The method 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.

Dr. Paul Corkum’s re-collision electron physics has led to many advances in understanding the interactions among coherent electrons, coherent light, and coherent atoms or molecules. The re-collision electron can be thought of as an electron interferometer built by laser light generated from atoms or molecules. As an interferometer, the re-collision electron can be used to measure atomic and molecular orbitals by means of interfering waves from the bound electrons and the re-collision electrons.
