UV Gas Laser Investigations

Abstract

The results of an intensive study of the high power characteristics of the Ar-N2 laser are described. A kinetic model predicting efficiencies as high as 4% is developed and contrasted to a series of experiments carried out concurrent with the calculations. Excitation, energy transfer, and energy levels are discussed. Laser energies as high as 0.23J at powers of 10 MW have been obtained with the Pulserad 535, a 3 MeV, 60 kA, 50 ns electron gun supplied by DNA. This output was obtained at an estimated efficiency of 2%. The laser oscillates on 2 lines, 3577A and 3805A, sequentially. The implications of this observation are discussed.
