✦ Synopsis

Polarized absorption spectra of Nd:LuVO 4 crystal were measured at room temperature. The optical parameters of π polarization and σ polarization were calculated by Judd-Ofelt theory. Meanwhile, the phenomenological intensity parameters: Ω 2 , Ω 4 , and Ω 6 were obtained, then the parameters were used to calculate the luminescence parameters of Nd:LuVO 4 crystal, including oscillator strengths, fluorescence branching ratio, radiative lifetime and integrated emission cross-sections. Experiments of a-cut and c-cut Nd:LuVO 4 lasers were also performed, and opt-opt conversion efficiency and slope efficiency were 40.3%, 50.5% for a-cut and 23.6%, 30.9% for c-cut, respectively.
