The invention relates to an optical resonator of a high-power CO2 gas laser. The optical resonator comprises a total reflecting mirror, a total reflecting mirror base, a total reflecting mirror gland cover, an output reflecting mirror, an output reflecting mirror base and an output reflecting mirror gland cover. The connection relationship is as follows: the optical resonator is installed and fixed on two end plates of a high-stability optical support and is fixedly connected with both ends of a chamber passage of a working gas circularly flowing in a closed mode through elastic adjustable bellows.
