Attosecond Science --from Gases to Solids

Paul Corkum

Professor of Physics
University of Ottawa

Attosecond pulses are generated by electrons that are extracted from a quantum system by tunneling in an intense light pulse and travel through the continuum. However, each electron can be forced to re-collide with its parent ion by the oscillating force of the time dependent electric field. Upon re-collision, the electron and ion are able to re-combine, emitting soft X-ray radiation. This highly nonlinear process occurs in atoms, molecules and solids and offers unique measurement opportunities – measurement of the attosecond pulses themselves; of molecular orbitals; and even the band structure of transparent solids.
