Abstract
We have previously developed a two-color above threshold ionization (ATI) model and used it to study the photoelectron spectra and the angular distribution of the photoelectron.1 We present calculations of the photon spectrum from recombination of the electron within the context of this model. The photon spectrum shows interesting and unexpected features that are determined by the nature of the continuum-continuum matrix element. The photon spectrum is contrasted with the photoelectron spectrum. We investigate these quantities for different ionization rates, laser pulse widths, and intensities of the redistribution laser, i.e., the laser responsible for the continuum-continuum transitions.
