摘　　要：Pr^3+-doped calcium niobium gallium garnet(Pr:CNGG)single crystals with different Pr^3+concentrations are successfully grown by the micro-pulling-down(μ-PD)method.The crystal structure,room-temperature absorption spectra,and fluorescence spectra of Pr:CNGG crystals are measured and discussed.The fluorescence results indicate their large dependence on the doping concentration.The fluorescence lifetime of the 1D2 energy level is also determined.The results indicate that Pr:CNGG crystal could be a potential solid-state laser gain medium.Pr3+-doped calcium niobium gallium garnet（Pr:CNGG） single crystals with different Pr3+concentrations are successfully grown by the micro-pulling-down（μ-PD） method.
