Abstract

In this paper are presented typical characteristics of supersonic CO-lasers and optimization results of energy loading into different gas mixtures using different electrode configurations. The development of discharge instability was investigated and strong influence of cathode configuration was found. Remarkably higher loading values measured in a static gas in comparison to a flowing one indicated the influence of the boundary layer. Hence an enlarged channel with a new electrode recessed into a cavity was investigated. As a result, improvement of medium homogeneity and higher laser output were achieved. Finally, the possibility of repetitively pulsing the system with respect to the clear-time of density disturbances is discussed.
