Abstract
Performance characteristics of a transverse-gas-flow cw CO2 laser in which dc discharge was sustained by simultaneous application of high-repetition-rate, high-voltage. short-duration electrical pulses are presented. This excitation scheme enabled maintaining a stable and uniform discharge with electrical input power density more than 15 W/cm3 in a typical laser gas mixture of 2 mbar CO2, 14 mbar N2, and 30 mbar He. Maximum laser power of 5.2 kW was obtained with 15% electrooptic efficiency from a pair of active regions each of 1-m length incorporated with a folded stable optical resonator. The effect of water vapor on laser performance is also discussed.
