An electrically excited CO2-N2laser has been developed using high repetition rate discharge pulses from a pin electrode array transverse to a supersonic flow. To date volumetric laser power density of 34 W/cm3from a Mach 3 flow at 17-kHz repetition rate and 160-torr static pressure has been achieved. Power densities of at least 150 W/cm3at atmospheric pressure appear possible. The supersonic blowdown facility and electrical pulse generator are described and experimental results are discussed.
