Abstract

The results are given of preliminary experiments carried out on a gasdynamic CO2 laser in which an N2–CO2–He working mixture of gases was heated in a plasmotron. A specific output energy 20 J/g and an efficiency ~1.2% were obtained for cw operation when the initial gas temperature was T0= 1700±100°K, the parameter poh* had the value ≲ 0.5 atm-cm, and the total flow rate of the gaseous mixture was ~0.5 kg/sec.
