Abstract

Polarized spectroscopic studies are reported of Nd³⁺ doped KLiYF₅ and Nd³⁺ doped KLiGdF₅--a new anisotropic mixed fluoride. Emission in the ⁴F_3/2 yields ⁴I_11/2 channel is strongly polarized. Explanations of the spectroscopic behavior are presented in terms of the local rare earth environment. Lifetime measurements of the ⁴F_3/2 state of Nd³⁺ ions in these monoclinic hosts and the dependence of fluorescence lifetime on dopant ion concentration are reported. Low threshold pulsed laser action was realized in both hosts with high efficiency, pumping with a long pulse Cr:LiSAF laser tuned to 797 nm.
