Abstract
The beam characteristics of the 2.4 kW industrial CO2 laser with the continuous current discharge and transverse gas flow have been studied depending on the main parameters of the telescopic resonator with the convex variable reflectivity mirror. The three-fold reduction of the beam divergence and the power decease only by 15 percent in comparison with the conventional stable resonator were obtained. Besides, the high degree of matching of the parameters of optical resonator and gas discharge chamber was reached.
