中文摘要	Nd-doped CaF2 crystal with high optical quality was obtained by a temperature gradient technique (TGT).Energies of the crystal field levels of Nd3+ multiplets relevant to laser operation were determined based on optical spectra recorded at T = 10 K. Room temperature absorption spectra were analyzed in the framework of the Judd–Ofelt theory to calculate radiative transition rates and luminescence branching ratios for the 4F3/2 level. The 4F3/2 radiative lifetime was calculated to be 1295 s whereas a monotonous decrease of the 4F3/2 luminescence lifetime value from 1.45 ms to 0.9 ms was observed when the temperature increased from 10 K to 300 K. The stimulated emission cross-section of 1.48×10？20 cm2 at 1061 nm was determined using the Fuchtbauer–Ladenburg relation. All the results showed that Nd:CaF2 would be a promising gain media in solid-state lasers.
