Gains of multicomponent working media in CO$_2$ gasdynamic lasers utilizing combustion products

An experimental study was made of the amplifying characteristics of working media having compositions which adequately represent those of fuel combustion products containing C, H, O, and N atoms. The atomic fractions of the elements ($\xi_i$) in the mixtures investigated were varied within the following limits: $\xi_ C/\xi_O\lesssim1$, and $\xi_N=0.6$. The experimental data are presented in the form of lines of equal gain on triangular C, H, O diagrams, for fixed values of the temperature and pressure in the gasdynamic-laser forechamber. The dependence of the gain on the initial parameters is analyzed.
