Abstract
Unfocused linear polarized laser light is used to explore ionization mechanisms in the region near three-photon resonances in Xe. In Xe-Ar and Xe-Kr mixtures at elevated concentrations, processes involving dimer absorption of third-harmonic photons are shown to play an important role in determining ionization yields, and a method for using the observed ionization to measure vacuum ultraviolet absorption is described.
