PROBLEM TO BE SOLVED: To obtain a gas laser oscillator capable of generating a stable laser output by decreasing discharge current ripple. SOLUTION: A gas laser oscillator comprising a discharge tube 1 provided with a light amplifying mirror at each end, circulating means for circulating a gas laser medium 6 inside the discharge tube 1, a pair of discharge electrodes provided respectively near both the ends of the discharge tube, a high voltage power supply connected between a pair of these discharge electrodes, and an auxiliary electrode 2 provided on the outer surface of the discharge tube 1 connected to the discharge electrodes. Here, the edge portion 21a of the auxiliary electrode 21 has an almost Rogouskii's electrode shape. |
