The paper is devoted to the investigation of full losses into the waveguide cavities that are platelet single crystals of semiconductors A₂B₆. Description of character of additional lines appearance in laser generation spectra is presented. It is shown that the section of symmetric waveguide which is the microlaser cavity creates such conditions of propagation and reflection from the facets for some transverse high-order modes that full losses coefficient of these modes at wavelength (lambda) becomes considerably less than the Urbach absorption coefficient at the same wavelength. The experimental researches of CdS single crystal generation spectra have been conducted and the interconnection between full losses and geometrical parameters of cavity have been established.
