Ionization of atoms in intense laser pulses using the Kramers-Henneberger transformation

Abstract

We present a general technique for the numerical calculation of the behavior of an electron in an intense laser field, by the direct integration of the time-dependent Schr\"odinger equation in the Kramers-Henneberger frame. We give results for a model potential; these include above-threshold ionization spectra for the transition regime to over-the-barrier escape. We also show how satellite spectra can develop in long pulses.
