Abstract

A two step model has been developed to describe the effects of a high brightness laser on the angular distributions of photoelectrons near and above threshold. The photoelectron production process and the transport of the electrons away from the ion are decoupled. The model predicts that the photoelectron distribution becomes more isotropic as the laser intensity increases. A larger laser intensity is required to perturb higher energy photoelectrons.
