Abstract
A laser oscillator having an enclosure serving as a vacuum vessel which is capable of preventing an electric discharge from occurring between a pair of electrodes and the inner surface of the vacuum vessel. The laser oscillator is made smaller in size, lower in total weight, and lower in manufacturing cost while securing a sufficient insulation gap between the electrodes and the inner surface of the vacuum vessel.
