Abstract

Results are presented of studies into possible improvement of the efficiency of sealed-off CO water-cooled lasers due to reduction of the total optical cavity losses. The experimentally achieved laser efficiency amounted to 18 - 20%, the output power being about 32 W. The maximum laser power was as high as 38.5 W. An effect has been studied of the temperature of the discharge tube walls on the efficiency and power per unit length. With the change in temperature from 40 to 1 degree(s)C, the laser emitter efficiency increased from 8.5 to 18% and the power per unit length rose from 13 to 31 W/m. The feasibility of further improvement in the efficiency of the sealed-off CO-lasers is briefly discussed.
