Paper Abstract

The results of the investigation of the beam quality in the high-power industrial carbon-dioxide laser generating in the 10 kW range are presented. As a result of this investigation, a scheme of the modified stable-unstable resonator is proposed, that uses only reflective mirrors. In this scheme, the plane of the unstable telescopic resonator is transverse to the flow in the discharge chamber. In the plane parallel to the electrodes this scheme represents a single-mode stable resonator. High efficiency of this resonator and high beam quality have been pointed out.
