Effect of medium composition on the output power from a fast-flow closed-cycle CO2 laser
V. P. Garashchuk, P. A. Vasilets
Abstract:
It is shown experimentally that for a constant total concentration C+CN (C is the CO2 concentration and CN is the nitrogen concentration), the product of the small-signal gain k0 and the saturation parameter Is does not depend on C and Is ~(C+CN)/C. This permitted us to obtain analytic expressions for the dependence of the laser radiation power on C and time if the rate of renewal of the medium and the CO2 dissociation and recombination rates are known. The expressions derived show fairly good qualitative and quantitative agreement with the experimental data. Recommendations are made for minimizing the reduction in the radiation power with time caused by the dissociation of CO2.
