`Special mirror' concept is presented as a `spare module' for a GaAs extracting mirror technological processed with GaAs thin films, mounted within two kinds of c.w. CO2 laser resonators: U-type resonator (with optical pathlength Lr equals 4 m) and U- type folded resonator with V-discharge on each branch, reversal mirror provided (with the optical pathlength Lr equals 8 m), experimentally used to obtain good quality laser beam. The extracting mirror presents variable reflectivity, acting as a super-Gaussian mirror and working as an output coupler in the resonator, providing total compensation of the refractive index and of the small gain asymmetries.
