✦ Synopsis

We present an interaction-picture time propagation method for the numerical solution of the time-dependent Schr6dinger equation in intense and superintense short-pulse laser fields. The method is tested on the problem of multiphoton and abovethreshold ionization (MPI/ATI) of a model C1-ion. It is seen that the interaction-picture approach leads to localized strongfield wavepackets, allowing the elimination of the boundary reflection problem as well as efficient and accurate treatment of the MPI/ATI dynamics and spectra.
