Abstract
СО2 lasers with transverse discharge and convective gas cooling find ever-increasing application. One strategy in making such lasers more efficient radiators is increasing the rate of the gas flow through the discharge zone with the help of diametral disk fans-heat exchangers. The application of such fans-heat exchangers, however, entails serious difficulties related to the glow discharge-gas flow interaction. In the present study, we investigate the stability problem for volume discharge in the gas loop of a СО2 laser with diametral disk fans-heat exchangers.
