Experiments have been conducted to study the applicability of a cw double-discharge stabilization scheme in conditions appropriate for high-energy lasers in supersonic flows. Steady arc-free volume discharges have been produced in a Mach 3 supersonic flow test cavity using an auxiliary discharge to stabilize the main discharge at low-current densities in N/sub 2/ and He/CO mixtures. A significant result is the lack of observed plasma E/N changes in response to auxiliary discharge current changes. Also, where glow discharges were obtained, the energy loading achieved was less than the threshold required for laser operation.
