An experimental and analytical study of a CO/sub 2/ supersonic mixing laser by N/sub 2/ axial glow discharge is presented. A cluster of supersonic and circular N/sub 2/ channels for axial glow discharge are employed to mix with CO/sub 2/ supersonic flow from conical screen nozzles. Small-signal gain measurement is conducted, together with monitoring discharge characteristics. Vibrationally nonequilibrium analysis of quasi-one-dimensional supersonic flow for the mixing laser is also presented, including N/sub 2/ collisional activation effects by electron impact in the glow discharge. Steady glow discharge in supersonic N/sub 2/ flow is obtained, and measured gain dependency on cavity flow distance, on plenum pressures, and on discharge power density in N/sub 2/ are discussed in comparison with numerically estimated characteristics. 11 references.
