This paper reports operation of an electron-beam excited atomic xenon laser investigated at pump rates between 40 W/cm{sup 3} and 1 kW/cm{sup 3} with pump times of 1 ms. Effects of cavity loss, gas mixture, and pump rate on laser performance were studied under selected conditions. The variation in laser power in 99.5% argon plus 0.5% xenon selectively lasing at 1.73 or 2.6 {mu}m was investigated as a function of pump power. It was found that the laser pulsewidth was shorter than the pump pulse and it increases as the pump rate decreased, consistent with a temperature induced effect. Lasing with broad-band optics was investigated as the xenon concentration was varied and as helium or neon was combined with argon-xenon mixtures. Strong lasing was observed for xenon concentrations up to 20%. Addition of helium resulted in a slight increase in laser pulsewidth and caused lasing at 2.03 {mu}m to increase at the expense of lasing at 1.73 and 2.6 {mu}m. Neon is as efficient as argon in producing lasing action. However lasing was not observed when no argon was included in the mixture.
