摘要：

The spectroscopic properties of Dy3+:LiGd(MoO4)(2) crystal have been investigated with aim to assess the feasibility of laser operation in the yellow region. On the basis of the analysis of polarized absorption spectra in the framework of the Judd-Ofelt theory, the main spectroscopic characteristics relevant for laser applications have been determined. An intense yellow emission band corresponding to the F-4(9/2) -> H-6(13/2) transition around 575 nm has been observed in the visible region. The emission cross-sections for the F-4(9/2) -> H-6(13/2) transition have been calculated using the Fuchtbauer-Ladenburg formula. The fluorescence and radiative lifetimes of the F-4(9/2) manifold are equal to 139.0 mu s and 199.1 mu s, respectively, and the quantum efficiency is 69.8%. (C) 2011 Elsevier B.V.
