Abstract

Comparative research works on spectral characteristics of monocrystals of Y₃Al₅O₁₂ doped with ions of rare-earth elements Pr³⁺, Nd³⁺, Eu³⁺, Ho³⁺, Er³⁺, Tm³⁺, monocrystals SrLaGa₃O₇ and SrLaAlO₄, doped with Nd³⁺, and LiNbO₃ doped with Er³⁺ obtained by the Czochralski method have been realized. Absorption spectra of these monocrystals have been determined in the range 200 nm divided by 20 micrometers and spectra of excitation and emission in the range 200 divided by 800 nm. Research works enabled us to estimate spectroscopic properties of these materials as active media on solid. Except for YAG:Eu⁺³ and LiNbO₃:Er⁺³ in all other materials an appearance of strong absorption bands in the range 780 divided by 840 nm has been stated as what enabled us to carry out an efficiency analysis of selective pumping with the use of laser diodes GaAlAs.
