Investigation of a laser-active D2–CO2–Ar mixture excited by a non-self-sustained discharge

The gain was determined for a D₂–CO₂–Ar mixture excited by a non-self-sustained discharge initiated by an electron beam. At low CO₂ concentrations (from 1 to 3 %) the gain ranged from 0.4 to 0.8 m ^– 1. The maximum specific energy which could be deposited in the mixture without disturbing its homogeneity amounted to 400 J · liter ^– 1 · atm ^– 1.
