ABSTRACT:
One partial reflecting mirror (19) and two total reflecting mirrors (21and23) being placed at one end of a resonator (12) and three total reflecting mirrors (20, 22, and24) being placed at an opposite end of the resonator (12) are included, and the reflecting mirrors (19, 21, and23and20, 22, and24) are placed so that the centers of laser light on the three reflecting mirrors (19, 21, and23; 20, 22, and24) placed at each end of the resonator forms a triangle. Two (19and21; 20and22) of the three reflecting mirrors (19, 21, and23; 20, 22, and24) placed at each end of the resonator (12) are placed at a downstream end of a discharge area in a direction in which a laser medium (10) flows.
