High-intensity nonlinear processes in the ultraviolet

Abstract

Information on the earlier studies concerning the ion and electron distributions, conducted at several different wavelengths, is thoroughly documented in Refs. 1-6. In addition, harmonic radiation6,7 and fluorescence6-8 produced in a gas jet by irradiation of atoms with intense UV radiation have been investigated. Specifically, measurements of short-wavelength radiation produced by intense UV (248-nm) irradiation (1015-1016 W/cm2) of the rare gases have revealed the copious production of fluorescence from excited levels. Strong fluorescence has been observed from ions of Ar, Kr, and Xe with the shortest wavelengths observed below 12 nm. These experimental findings on the ions, electrons, and radiation produced give information on the coupling mechanism governing the nonlinear interaction.
