Numerical simulation of a CO laser pumped by a medium-pressure combined discharge

A model of a pulsed CO laser pumped by a medium-pressure combined discharge at room temperature is discussed. The optimum parameters of the active medium (pressure, specific energy input, and the ratio E/p for different mixtures) at which the calculated efficiency for a mixture with the composition CO:He=1:3 amounts to 14% are calculated. The dependence of the output parameters on the additions of nitrogen and xenon to the working mixture is analysed.
