ラー形ガスレーザ発振器。[Claims for Utility Model Registration] 1. A gas laser tube consisting of a discharge capillary and a pair of Brieusta windows connected to both ends of the discharge capillary,
In an external mirror type gas laser oscillator, the external mirror type gas laser oscillator has a pair of laser mirrors constituting a gas laser tube and an optical resonator, a mirror support for holding the laser mirror, and a dustproof cover that protects the Breustar window and the laser mirror from dust. A cylindrical part A that has an inner diameter that encloses a window and is hermetically fixed to the mirror support body, and a cylindrical part B that has the same diameter as the cylindrical part A and that is hermetically fixed to the gas laser tube are placed on opposing cylinder end faces on the circumference. between the cylindrical part A and the cylindrical part B, a bellows part made of a metal material that encloses the Brieusta window and is contractible in the direction of the laser optical axis is fitted into the cylindrical end groove. An external mirror type gas laser oscillator characterized by being fixed in a closed state. 2. The external mirror type gas laser oscillator according to claim 1, wherein the bellows component is made of Teflon.
