| Abstract: | We suggest a variant, which has already been implemented, of a selective intracavity laser spectrometer with intracavity nonlinear
optical conversion of the frequency range of generated multimode radiation. The apparatus provides a means for transition
into the UV spectral range (shorter than 300 nm) to carry out direct recording and quantative investigation of strong resonance
lines of atomic absorption, which earlier were beyond the reach of the intracavity method. We measured selective absorption
in spectral lines of a number of metals: FeI 296.690 nm, TiI 294.200 nm, and GaI 287.424 nm.
