It is shown experimentally that a transverse rf discharge in tubes has a higher plasmachemical activity than a dc discharge, which deteriorates the parameters of rf discharge-pumped CO{sub 2} lasers. The output power and efficiency of a sealed off CO{sub 2} laser were substantially increased by using a distributed gold catalyst facilitating CO{sub 2} regeneration. The output power of 0.77 W cm{sup -1} per unit length of an active medium with efficiency of 18.5% was obtained in an experimental CO{sub 2} laser with tubes with a distributed gold catalyst pumped by a 27.1 MHz rf discharge.
