Paper Abstract

The variable reflectivity mirror whose behavior was followed in dynamic regime while used in C.W. CO2 technological laser had the structure: AIR (ZnSe, BaF2)/GaAs(ZnS)AIR acting as a super-Gaussian mirror. It worked as an output coupler in an U type resonator mounted in a C.W. CO2 transverse flow laser, the output power characterizing the emitted beam belongs to the interval 800 - 1000 W in the fundamental mode. Following 300 hours of operations, in technological regime and 600 hours of overall operation, the laser beam quality exhibited unmodified characteristics from the point of view of industrial processing of materials.
