Pulsed Inductive IR Ar I laser

Abstract

The results of experimental studies of the effect of pumping conditions on the spectral and temporal characteristics of IR Ar I laser radiation under excitation of the active medium by longitudinal pulsed inductive discharge are presented. The lasing was obtained at transitions of neutral argon atoms at wavelengths of 1213, 1240, 1270, 1694, and 1791 nm in pure argon and in its two-component mixtures with helium and neon. The optical pulse length at half maximum was (5 ± 1) ns. The radiation energy attained 0.1 mJ.
