The polarized absorption spectra of Nd:LuVO₄ crystal was measured at room temperature. The optical parameters of π polarization and σ polarization were calculated by Judd-Ofelt theory. Meanwhile, the phenomenological intensity parameters were obtained, then the parameters were used to calculate the luminescence parameters of Nd:LuVO₄ crystal, including oscillator strengths, fluorescence branching ratio, radiative lifetime and integrated emission cross-sections. The experiment of a-cut and c-cut Nd:LuVO₄ 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.
