Paper Abstract

The aim of this paper consists in estimating the influence of the intensity of radiation field enterin back the active cavity of a cw gasdynamic source laser after being reflected by the target surface. It is shown that this back reflected beam increases the source laser efficiency (net output power) and, ny the same token, the thermal load of its cavity mirrors. It changes significantly the range of the source laser transmittivity admissible values. The lower bound of the reflectivity of a cw gasdynamic laser resonator decreases. The upper bound of the same, parameter coincides with its value at which the emitted light energy goes theoretically ad infinitum causing destruction of the source laser. It is suggested that mentioned effects are the result of the hybryde, generator - master oscillator power amplifier, conditions at which the source laser active cavity is operating.
