The intracavity diffraction in a multifrequency laser filter with a matched extra dispersion device and a two-wave photoelastic grating is investigated. The opportunity to suppress a hybrid component with an increase in the intensities of basic components in the spectrum of a multifrequency laser is proved if the sound frequency differences are greater than the critical value. The regularity of diffraction and the role of multiphonon processes are determined.
