Abstract

We investigate the influence of electron correlation in the double ionization of a two-electron model atom exposed to an intense laser field. Using the freedom of our model system, we vary in a systematic way the correlation strength between the two electrons. For the case of five-photon ionization, while adjusting the laser frequency according to the correlation charge, we investigate extreme situations of strong and weak two-electron interaction regimes. We monitor the single and double ionization yield and study the variation of the nonsequential ionization.
