Gasdynamic laser using a D2–HCl–He mixture

Gasdynamic lasers using a D₂–HCl–He mixture are discussed theoretically. A numerical analysis is used to investigate in detail the dependence of the gain on the initial parameters, nozzle contour, and mixture composition. It is found that, under the optimum operating conditions, the gain can reach values of 10^–2–10^–1 cm^–1.
