Abstract: A three-mode method for the separation of frequency resonances in a laser with a nonlinear absorbing medium is proposed. The results are reported of a study of frequency resonances in an He–Ne/I₂ laser emitting the wavelength of 0.63μ. It was found that the three-mode method ensures considerable enhancement of the frequency resonance gain compared with the two-mode method, which is desirable in spectroscopic applications of lasers and in the stabilization of the laser emission frequency.
