Abstract

By optimizing the discharge parameters of a pulsed HCN laser, peak powers up to 1 kW have been obtained with the output radiation predominantly in the lowest transverse mode. The production of discharge impurities at high input power limits the long-term repetitive operation to 450-W output. Details of the variation of power with discharge voltage, repetitive rate, gas composition, and flow rate are given, and suggestions for further increasing the power are made.
