Paper Abstract

Results of experimental investigations of output power and beam divergence for a slab waveguide rf-excited carbon- dioxide laser are presented. Laser output power 150 - 250 W and maximum efficiency 10 - 13% in a beam with near- diffraction-limit divergence has been achieved. In repetitive-rate mode, the pulsed power was more than twice as much as the average one in the cw mode. After beam shaping lens, the sum beam divergence of 2.5 mrad at the 0.8 total power level has been obtained.
