Claims

[Scope of utility model registration request]

(1) A resonant mirror holding mechanism for attaching a resonant mirror facing into the excitation tube to both ends of an excitation tube filled with laser gas, the support being supported at the ends of the excitation tube via a support mechanism. a plate; an insulating ring having an outer circumferential support plate abutting surface that abuts the inner surface of the supporting plate and fixed to the shaft of the supporting plate; an inner circumferential portion formed on the inner step of the insulating ring; a resonant mirror whose inner surface is in contact with a mirror abutment surface; a mirror holding ring that is inserted into the insulating ring from the outside and fixes the resonant mirror; A resonant mirror holding mechanism for a laser oscillator, characterized in that it is located on substantially the same plane as a peripheral mirror abutment surface.

(2) Utility Model Registration In Claim 1, the support mechanism for the support plate includes a spring means for urging the support plate toward the excitation tube, and a spring means for holding the support plate in a fixed position against the spring means. A resonant mirror holding mechanism for a laser oscillator consisting of three or more support rods protruding from the excitation tube side.

(3) Utility Model Registration The resonant mirror holding mechanism for a laser oscillator according to claim 1 or 2, wherein the support plate is provided with a series of cooling medium inlets, cooling channels, and exhaust ports.
