Abstract
A simple mathematical model is used in numerical analysis of the characteristics of a gasdynamic laser utilizing selective excitation and supersonic mixing. The dependences of the specific gain and specific energy output on various parameters are deduced. The calculated temperature dependence of the specific gain, is in agreement with the experimental data to an accuracy sufficient for preliminary estimates. Calculations of the specific energy output of a gasdynamic laser utilizing mixing, provide an explanation of the experimentally recorded tendency for the optimal initial temperature to rise on increase of the helium concentration in the injected mixture.
