Paper Abstract

A long time stable operation of a high-power discharge-excited CO laser was attained by controlling a laser gas composition. Firstly, changes of the gas composition during discharge under the sealed-off condition were studied experimentally. On the basis of these results, the conditions of a gas exchange, which lead to the stabilization of the output laser power, were determined. A continuous operation of the CO laser about 1 hour at a power level of 3 kW was achieved with a power instability less than +3 %.
