Powerful electroionization laser on Xe infrared atomic transitions

Abstract

A powerful pulsed high-pressure Ar-Xe laser with an active volume of 91 is studied. Laser output energies of 5.8 J for electron-beam pumping and 19 J for electroionization pumping are attained. The laser power exceeds 13 MW. More than 95 percent of the output laser energy is concentrated in the line with <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\lambda = 1.73 \mu</tex> m. Efficiencies greater than 5 percent were observed.
