The 0.6 at.％Pr3+-doped CaF2-YF3 crystal was successfully grown by the temperature gradient technique(TGT).X-ray diffraction analysis showed that the grown crystal still had cubic structure.The absorption spectrum,emission spectrum,Judd-Ofelt analysis and fluorescence decay curve at room temperature were discussed.The fluorescence lifetime of Pr:CaF2-YF3 crystal was 45.46 μs,and the σem·τ of 3P0 →3H6 and 3P0 →3F2 transitions were calculated to be 80.92×10-20 cm2.μs and 388.7×10-20 cm2·μs,respectively.The FWHMs are 20.1 nm and 6.8 nm,which are higher than those of Pr:LiYF4,Pr:LiLuF4,Pr:LiGdF4 and Pr:BaY2F8 crystals.The results show that the Pr:CaF2-YF3 crystal is expected to achieve 605 nm orange light and 642 nm red light laser operation.
