Abstract
A double-electron-ionization process occurs when an intense laser pulse interacts with atoms or molecules. Exact ab initio numerical simulation of such a situation is extremely computer resource demanding, thus often one is forced to apply reduced dimensionality models to get insight into the physics of the process. The performance of several algorithms for simulating double electron ionization by strong femtosecond laser pulses is studied. The obtained ionization yields and the momentum distributions of the released electrons are compared and the effects of the model dimensionality on the ionization dynamics are discussed.
