Investigations of spectroscopic properties of yttrium-aluminum garnet Y3Al5O12 (YAG) doped with Ce, Pr, Nd, Sm, Eu, Ho, Er, Tm, Yb ions and Nd:YAP, Nd:SrLaGa3O7, Nd:SrLaAlO4, Nd:YVO4, Nd:LiYF4, Nd:PbMoO4, Nd:LGS, Nd:GGG, Nd:SVAP monocrystals have been realized. Absorption spectra of the monocrystals in the range 200 nm - 20 micrometer and the luminescence spectra in the range 200 - 800 nm for Pr:YAG, Pr:YAP and Pr:SrLaGa3O7 were determined. Except for Pr:YAG, Sm:YAG, Eu:YAG and Pr,Yb:YAG in all other materials an appearance of strong absorption bands in the range of 780 - 840 nm has been stated that enabled us to carry out an efficiency analysis of selective pumping with the use of GaAlAs laser diodes.
