Abstract
We present an interaction-picture time propagation method for the numerical solution of the time-dependent Schrödinger equation in intense and superintense short-pulse laser fields. The method is tested on the problem of multiphoton and above-threshold ionization (MPI/ATI) of a model Cl- ion. It is seen that the interaction-picture approach leads to localized strong-field wavepackets, allowing the elimination of the boundary reflection problem as well as efficient and accurate treatment of the MPI/ATI dynamics and spectra. © 1992.
