Abstract
In recent years there have been very significant advances in short pulse, high intensity laser technology. Lasers with pulse lengths of 0.1–1 ps and wavelengths from 0.2–1 μm can be focused to produce intensities from 1012 to above 1018 W/cm2. One major use of these systems has been for studies of the response of atoms and molecules to such intense, well characterized electromagnetic fields. Because these pulses are very short, neutral atoms can survive to experience intensities where theoretical treatments based on the traditional perturbation expansion of the wave function in terms of the field-free states will fail completely to describe the dynamics of the system. An explicit, non-perturbative time-dependent calculation is one approach which can represent these strong field effects.

We note that Paul Corkum has independently extended his quasi-static model (Ref. 16) also along these lines to consider both harmonic generation and impact ionization of the ion core by returning electrons.
