PROBLEM TO BE SOLVED: To obtain a gas laser oscillator in which the design margin of a discharge electrode is widened and the product is stabilized. SOLUTION: The gas laser oscillator comprises a gas laser housing for encapsulating laser gas, means for circulating the encapsulated laser gas in the gas laser housing, a pair of electrodes for discharging the gas by applying a voltage to the laser gas at a specified position of the circulating laser gas, and a discharge power supply connected with the pair of discharge electrodes and feeding the discharge electrodes with a voltage for discharging the laser gas, wherein the wall material constituting the housing is composed of a dielectric material at at least a part corresponding to a specified position and the pair of discharge electrodes are buried in the wall material composed of the dielectric material. |
