通过单晶陶瓷化得到透明Nd掺杂Ca1−xYxF2+x陶瓷，并对其形貌、显微结构特征、光学性能和激光性能进行了研究。结果表明，透明 Nd 掺杂 Ca1−xYxF2+x 陶瓷的微观结构与传统热压 CaF2 陶瓷相似。此外，透明 Nd 掺杂 Ca1−xYxF2+x 陶瓷表现出与前驱体单晶相同的光学性能。此外，前驱体单晶的陶瓷化制备了透明的Nd掺杂Ca1−xYxF2+x陶瓷，其机械性能（显微硬度H=3.430GPa，断裂韧性K1c=0.61MPam1/2）优于Nd掺杂Ca1−xYxF2+x单晶。通过应用中心波长约为 808 nm 的光纤耦合激光二极管，获得了输出功率为 35 mW 的连续波激光操作。这表明本研究中制造的透明 Nd 掺杂 Ca1−xYxF2+x 陶瓷是二极管泵浦固态激光器和激光放大器的有希望的候选材料。
Transparent Nd-doped Ca1 − xYxF2 + xceramics were obtained through the ceramization of single crystals, and the morphology, microstructural characteristics, optical properties, and laser performance of the ceramics were examined. The results indicated that the microstructure of the transparent Nd-doped Ca1 − xYxF2 + xceramics was similar to that of traditional hot-pressed CaF2ceramics. In addition, the transparent Nd-doped Ca1 − xYxF2 + xceramics exhibited the same optical properties as the precursor single crystals. Furthermore, the ceramization of the precursor single crystals produced transparent Nd-doped Ca1 − xYxF2 + xceramics with mechanical properties (microhardnessH= 3.430 GPa, fracture toughnessK1c= 0.61 MPa m1/2) that were superior to that of the Nd-doped Ca1 − xYxF2 + xsingle crystals. Continuous-wave laser operation with an output power of 35 mW was obtained through the application of a fiber-coupled laser diode with a central wavelength of approximately 808 nm. This suggests that the transparent Nd-doped Ca1 − xYxF2 + xceramics fabricated in this study are promising candidates for diode-pumped solid-state lasers and laser amplifiers.
