摘要:

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. 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.

关键词: Pr:CNGG, μ-PD method, spectral properties
