Abstract

Investigation of spectroscopic properties of yttrium-aluminum garnet Y₃Al₅O₁₂ (YAG) doped with ions of rare-earth elements Ce³⁺, Pr³⁺, Nd³⁺, Sm³⁺, Eu³⁺, Ho³⁺, Er³⁺, Tm³⁺, Yb³⁺ monocrystals yttrium-aluminum perovskite YAlO₃ (YAP), SrLaGa₃O₇ (SLGO) and SrLaAlO₄ (SLAO) doped with Nd³⁺, and LiNbO₃ doped with Er³⁺ and Tm³⁺ obtained by the Czochralski method have been realized. Absorption spectra of the monocrystals were determined in the range 200 nm divided by 20 micrometers as well as luminescence spectra in the range 200 divided by 800 nm. Research works enabled to estimate spectroscopic properties of these materials as active media for solid state lasers. Except for YAG:Pr³⁺, YAG:Sm³⁺, YAG:Eu³⁺ and YAG:Pr³⁺,Yb³⁺ in all other materials an appearance of strong absorption bands in the range 780 divided by 840 nm has been stated what enabled to carry out an efficiency analysis of selective pumping with the use of laser diodes GaAlAs.
