Abstract

For a dc self-sustained discharge adapted for excitation of a transverse-flow 1.2 kW CO₂ laser stable operating condition in a CO₂/N₂/He equals 1/9/15 mixture at static pressure of 30 - 40 Torr and by flow velocity up to 70 m/s were obtained in the excited volume of 2.1 dm³ by the dissipated electric power density up to 9.5 W/cm³. It has been confirmed that the passivation and conditioning of electrodes influences strongly the long-term output characteristics.
