Photoemission spectra from autoionizing states under recycling conditions

Abstract

Spectral features of the radiation emitted by autoionizing states in the presence of a strong laser field are calculated under the condition of multiple photon absorption and emissions. The method is based on the exact solution of the master equation for the recycled system. The decay spectra are found to exhibit sharp maxima at the laser frequency and, for large values of the Fano $q$ value, sidebands which are reminiscent of the triplet which one finds in the context of a two-level atom.
