Paper Abstract

Results of investigations of output power and beam divergence for a slab waveguide rf-excited carbon-dioxide laser are presented. Laser output of range 200 W and efficiency about 10% in a beam with near-diffraction-limit divergence has been achieved. In the repetitive-rate mode, the pulsed power was more than twice as much as the average one in the cw mode. After beam shaping telescope, the total beam divergence of 2-3 mrad at the 0.8 power level has been obtained.
