EXPERIMENTAL INVESTIGATION AND COMPUTER-S IMULATION OF RF-EXCITED SLAB WAVE-GUIDE CO LASER

Results of investigations of a slab waveguide RF-excited CO laser are presented Laser output mean power of 160 W and efficiency about 10% in a beam with near-diffraction-limit divergence has been achieved. In t he repetitive-pulse,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 obta ined. Codes package of computer simulation of CW slab RF-excited diffu sion-cooled CO-laser was created. Comparison of calculated and experim ental data has been fulfilled.
