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.
