Analysis of absorption spectra of the crystals for coherent radiation pumped solid state lasers

摘要

Abstract: Investigations of spectroscopic properties of yttrium-aluminium garnet Y$-3$/Al$-5$/O$-12$/ (YAG) doped with Ce, Pr, Nd, Sm, Eu, Ho, Er, Tm, Yb ions and Nd:YAG, Nd:SrLaGa$- 3$/O$-7$/, Nd:SrLaAlO$-4$/, Nd:YVO$-4$/, Nd:LiYF$-4$/, Nd:PbMoO$-4$/, Nd:LGS, Nd:GGG, Nd:SVAP monocrystals have been realized. Absorption spectra of the monocrystals in the range 200 nm $DIV 20 $mu@m and the luminescence spectra in the range 200 $DIV 800 nm 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 $DIV 840 nm has been stated what enabled to carry out an efficiency analysis of selective pumping with the use of GaAlAs laser diodes.!9
