Attosecond Pulses Generated in Gases and Solids

P.B. Corkum Joint Attosecond Science Lab University of Ottawa and National Research Council of Canada

Abstract: Attosecond pulses are generated by electron wave packets that are extracted from a quantum system by an intense light pulse and travel through the continuum under the influence of the electric field of the light. Portions of each electron wave packet are forced to re-collide with its parent ion after the field reverses direction. Upon re-collision, the electron and ion can recombine, emitting soft X-ray radiation that can be in the form of attosecond pulses. This highly nonlinear process occurs in atoms, molecules and solids and offers unique measurement opportunities – for measuring the attosecond pulse itself; the orbital(s) from which it emerged; and the band structure of material in which the wave packets moved.

Bio: Dr. Corkum is a fellow of the Royal Societies of Canada and London; a foreign member of the US, the Austrian and the Russian Academy of Science. In 2013, he was awarded Saudi Arabia’s King Faisal Prize for science and Israel’s Harvey Prize for physics. In 2014 he was named “Thompson Reuters Citation Laureate for work that is of Nobel class and likely to earn the Nobel someday”. In 2018 he received the SPIE Gold medal and the IOP’s Newton Medal, both societies’ highest awards.
