Abstract The Qprop package is presented. Qprop has been developed to study laser–atom interaction in the nonperturbative regime where nonlinear phenomena such as above-threshold ionization, high order harmonic generation, and dynamic stabilization are known to occur. In the nonrelativistic regime and within the single active electron approximation, these phenomena can be studied with Qprop in the most rigorous way by solving the time-dependent Schrödinger equation in three spatial dimensions. Because ... Title of program: QPROP Catalogue Id: ADXB_v1_0 Nature of problem Atoms put into the strong field of modern lasers display a wealth of novel phenomena that are not accessible to conventional perturbation theory where the external field is considered small as compared to inneratomic forces. Hence, the full ab initio solution of the time-dependent Schrödinger equation is desirable but in full dimensionality, only feasible for no more than two (active) electrons. If many-electron effects come into play or effective ground state potentials are needed, (time-depend ...
