11が発振する。Conventionally, in order to stabilize optical output in a laser device, a member having an extremely small coefficient of thermal expansion has been used for an optical resonator support. That is, as shown in FIG. 1, a laser power source is connected between the cathode 2 and anode 3 of the laser tube 1,
A discharge is caused between the cathode 2 and anode 3 of the laser tube 1, and the laser beam 11 is emitted by an optical resonator consisting of a mirror 4.4' supported by a resonator support 5.5' and a spring support 6.6'. oscillate.

る欠点がめる。However, the mirror support 6.6', the mirrors 4, 4' and the resonator support 5.5', the laser tube 1 are
.. 7', the resonator support 5.5' must be mechanically strong, and must be made of super-i/barrond with a small temperature coefficient (outer diameter of 10-odd ξ meters). etc. are used. This results in a large, complex, and heavy device, which has the drawback of increasing the material cost of the resonator support 5,5'.

The laser beam 10 is oscillated by the optical resonator 4.4'. Further, a heat insulating oil passage device 9 is provided on the aluminum die-cast resonator support 8, and the heat insulating oil 10 is circulated to control the temperature of the resonator support 8 to approximately 40° C. and 11° C.
