Different deformation rates of Nd,Y-codoped CaF₂ transparent ceramics were prepared by ceramization of single crystals. The deformation rate effects on the crystallization behaviors, microstructures, mechanical properties, and optical performances were investigated for the first time. The results indicate that the comprehensive performances of Nd,Y-codoped CaF₂ ceramic (△a = 62%) are the most optimal compared with other ceramics having different deformation rates (△a = 34%, 40%, 50%, and 75%). In further investigations of the optical properties, the Nd,Y-codoped CaF₂ ceramic (△a = 62%) sample exhibited a high transparency (T_a > 91%, 3-mm thick，250 ∼ 1200 nm), low light scattering, superior fracture toughness (K_1c ∼ 0.71 MPa·m^1/2), strong fluorescence emission, long lifetime (τ = 348.72 μs), and broad FWHM (29.2 nm), promising a good candidate for high-power laser material.

通过单晶陶瓷化制备了Nd，Y掺杂的CaF ₂透明陶瓷不同的变形速率。首次研究了变形速率对结晶行为，微观结构，力学性能和光学性能的影响。结果表明，与其他具有不同变形率（△a = 34％，40％，50％和75）的陶瓷相比，掺Nd，Y掺杂的CaF ₂陶瓷（△a = 62％）的综合性能最佳。 ％）。在进一步研究光学性能时，掺钕，钇掺杂的CaF ₂陶瓷（△a = 62％）样品表现出高透明度（T _a  > 91％，3毫米厚，250〜1200纳米），低光散射，优异的断裂韧性（K _1C  〜0.71兆帕·米^1/2），强的荧光发射，长寿命（τ= 348.72微秒），和宽FWHM （29.2 nm），有望成为高功率激光材料的理想选择。
