<p>A gas laser oscillator which realizes a high output and takes out a stable laser beam; and a gas laser processor using this gas laser oscillator. The gas laser oscillator has a discharge excitation section (5) having at least a pair of discharging electrodes (1a, 1b), mirror unit sections (8a, 8b) for holding resonator mirrors connected to the discharge excitation section, and gas blowers (11, 12) inside or outside of the mirror unit sections. In the gas laser oscillator of such structure, absorption of laser beams generated in the mirror unit sections may be eliminated by circulating laser gases existing in the mirror unit sections (8a, 8b) using the gas blowers (11, 12).</p> |
