本発明はガスレーザ管に関し、特に共振器用ミラーを傑
物したガスレーザ管に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a gas laser tube, and more particularly to a gas laser tube that features a resonator mirror.

る。Conventionally, this type of gas laser tube consists of an envelope made of glass or the like that has a narrow tube such as EleOm and laser discharge components such as a cathode inside, and a pair of light beams simply attached to both ends of the envelope. The structure consists of a resonator mirror.

点を有していた。However, in the conventional gas laser tube described above, the configuration is such that a pair of optical resonator mirrors are simply attached to both ends of the envelope, so the angle of the optical resonator mirrors described above is adjusted so that the laser output is maximized. Alternatively, after cleaning the outer surface of the mirror, when handling the laser tube in order to mount it in a device or move it, place a portion of this optical resonator mirror against an object to optimize the angle adjustment. This has the disadvantage that the mirror may shift from the correct position or the outer surface of the mirror may come into contact with foreign matter, resulting in the laser output not being at its maximum or the output stability being deteriorated.
