A study was made of a copper vapor laser pumped by a radial transverse discharge at pressures of up to 1.5 atm. It was found that a sufficient reduction of the parasitic inductance of the laser discharge circuit could ensure a high efficiency. A physical efficiency of 5.3% was achieved. It was also found that the use of vaporizers enabled substantially improved output parameters to be obtained for a laser with a radial transverse discharge. It was established that by circulating the Cu--Ne active mixture one could overcome the limitation imposed on the pump power by the release of heat in the Cu-laser active medium. Lasing was produced in copper vapor using a pulsed hollow-cathode discharge. The laser output power was 1.2 W and a physical efficiency of 5% was achieved, while the specific output power energy was 15 ..mu..J/cm/sup 3/.
