Spectroscopic properties of yttrium-aluminium garnet Y3Al5O12 (YAG) do
ped with Ce, Pr, Nd, Sm, Eu, Ho, Er, Tm, Yb ions and Nd:YAP, Nd:SrLaGa
3O7, Nd:SrLaAlO4 Nd:YVO4, Nd:LiYF4, Nd:PbMoO4, Nd:LGS, Nd:GGG, Nd:SVAP
monocrystals have been investigated. Absorption spectra of the monocr
ystals in the range of 200 nm-20 mu m and the luminescence spectra in
the range of 200-800 nm for Pr:YAG, Pr:YAP and Pr:SrLaGa3O7 were deter
mined. Except for Pr:YAG, Sm:YAG, Eu:YAG and Pr, Yb:YAG, in all other
materials strong absorption bands appeared in the range of 780-840 nm,
which enabled an efficiency analysis of selective pumping to be carri
ed out with the use of GaAlAs laser diodes.
