Abstract

PURPOSE:To stabilize oscillation by maintaining a CO concentration at the optimum value by providing a sensor detecting gas status in a circulatory passage in a carbon dioxide laser device providing an oxidizing catalyst in the gas circulatory passage wherein the heating temperature of the catalyst is established. CONSTITUTION:A carbon dioxide laser unit is composed of a laser oscillation section 21 and a gas circulatory regeneration section 22. Discharge is performed by the laser oscillation section 21 and CO concentration of the gas having increased CO concentration is reduced by an oxidizing catalyst 12. Then, the gas is cooled by a heat exchanger 2 to feed to the laser oscillation section 21 again by increasing the pressure by a blower 1. In increasing the CO concentration, a sensor 18 detects to raise the temperature of the oxidizing catalyst 12 by controlling a power source 15 for heater and a coefficient of CO oxidation is increased. On the other hand in decreasing the CO concentration, the temperature of the catalyst 12 is lowered. As the result, the CO concentration in gas will be maintained at the optimum value for performing stable oscillation.
