Time-dependent generalized pseudospectral method for accurate treatment of multiphoton processes of diatomic molecules in intense laser fields. (English) Zbl 1219.81275

Summary: We present a numerical method based on the generalized pseudospectral discretization in prolate spheroidal coordinates and split-operator time propagation. The method has been applied for the study of multiphoton processes of \(\text{H}_2^+\) and \(\text{N}_2\) diatomic molecules in intense laser fields. It proves very accurate while using only moderate computer resources.
