Power resonances at the centers co+ and ω_ of the amplifying and absorbing components respectively, were obtained simultaneously for a ring helium-neon laser with a nonlinear absorbing cell. By varying the pressure in the amplifying medium, these resonances can be made to coincide with accuracy ~104 Hz, thus uncovering a possibility of obtaining a high reproducibility, ~10~15 in terms of the parameter (ω+ — ω_), of the frequency of gas lasers.
