采用提拉法在氮气气氛下成功地生长了Pr 3+掺杂Sr 0. 5La 0. 5 Mg 0. 5Al 11. 5 O 19（ASL）晶体<100>。在室温下测量了Pr：ASL晶体的吸收光谱和发射光谱。在InGaN激光二极管泵浦下，a切和c切Pr：ASL样品的连续波激光操作已经被证明。对于726 nm深红色激光，a切样品的最大输出功率为92.8 mW，斜率效率为11.9%，c切样品的最大输出功率为46.6 mW，斜率效率为8.0%。对于波长为645 nm的红光，a切和c切样品的最大输出功率分别为49.2 mW和42.8 mW，斜率效率分别为6.7%和8.5%。
Pr3+-doped Sr0.5La0.5Mg0.5Al11.5O19(ASL) crystal along <100> direction was successfully grown using the Czochralski technique under azote atmosphere. Absorption and emission spectra of Pr:ASL crystal have been measured at room temperature. Continuous-wave laser operation of the a-cut and c-cut Pr:ASL samples under InGaN laser diode pumping has been demonstrated. For deep red laser operation at about 726 nm, the maximum output powers achieved from a-cut sample was 92.8 mW with slope efficiency of about 11.9%, while 46.6 mW with slope efficiency of 8.0% for the c-cut sample. For red laser at about 645 nm, maximum output powers of 49.2 mW and 42.8 mW were obtained for the a-cut sample and c-cut sample, corresponding to a slope efficiency of 6.7% and 8.5%, respectively.
