用提拉法成功地生长出了高光学质量的Yb，Ho：YAP和Yb，Ho，Pr：YAP激光晶体。由于Yb3+敏化剂的掺杂，两种晶体在970 nm处的吸收系数和带宽都有所增加。这两个晶体的三个最强的荧光峰分别位于约2844、2853和2912 nm，对应于Ho3+离子的5I6→5I7能级跃迁。寿命测量表明，减活剂Pr3+离子可以有效地将低能级5I7的寿命从8.848毫秒降低到1.258毫秒。对能量传递机制进行了研究和分析，上转换发光光谱进一步证明Pr3+离子可以有效地在5I7能级上去布居Ho3+离子。这些结果表明，Yb，Ho，Pr：YAP晶体有望成为实现970 nm激光二极管泵浦的2.8~3.1nMμm激光器的理想激光介质。
Yb,Ho:YAP and Yb,Ho,Pr:YAP laser crystals with high optical quality are successfully grown using the Czochralski method. The absorption coefficient and band width of the two crystals at 970 nm are increased because of the doping of Yb3+sensitizer. The three strongest fluorescence peaks of the two crystals are located at approximately 2844, 2853, and 2912 nm, which correspond to the5I6→5I7level transitions of Ho3+ions. Lifetime measurements indicate that the deactivator Pr3+ions can efficiently decrease the lifetime of the lower level5I7from 8.848 ms to 1.258 ms. Energy-transfer mechanisms are also studied and analyzed, and up-conversion luminescence spectra provide the further evidence that Pr3+ions can efficiently depopulate Ho3+ions at the5I7level. All these results show that Yb,Ho,Pr:YAP crystal may be a promising laser medium for realizing 2.8–3.1 μm lasers pumped using a 970 nm laser diode.
