Abstract

A gas laser oscillation apparatus wherein, in order to prevent a center axis of a reflecting mirror included in a laser resonator from deviating from an optical axis of the laser resonator due to the deformation of a mirror supporting frame caused by a vacuum force applied to a laser tube, the reflecting mirror is fixed to a mirror holding plate, which is attached to the mirror supporting frame with fasteners such as bolts and nuts.
