Atomic RABBITT-like experiments assisted by a circularly polarized laser

Abstract

SynopsisWe study theoretically the single ionization of atoms by the combined action of an attosecond pulse train with linear polarization and an assistant laser field with circular polarization. By means of a non-perturbative model, we obtain closed-form expressions for the angular distributions of photoelectrons. We show that such a configuration of light fields is similar to the usual polarization control technique where both the attosecond pulse train and the assistant laser field are linearly polarized with a controlled relative orientation.
