The Tm,Ho:YAlO3 laser performance for two crystal orientations pumped by a wavelength tunable Ti:Sapphire laser is presented in this paper. An experimental investigation comparing a- and b-oriented Tm,Ho:YAlO3 crystals laser performance is demonstrated and discussed. Single- and multi-wavelength operations of Tm,Ho:YAlO3 lasers have been investigated in detail. The maximum output powers of 890 mW at 2119 nm for a-oriented Tm,Ho:YAlO3 crystal and 946 mW at 2103 nm for b-oriented Tm,Ho:YAlO3 crystal have been obtained, respectively. The two crystals show very similar performance in terms of output power and conversion efficiency, only that the b-cut Tm,Ho:YAP crystal demonstrates more regimes of multi-wavelength operations.
本文介绍了由波长可调谐钛宝石激光器泵浦的两种晶体取向的Tm,Ho:YAlO3激光器的性能。展示并讨论了对a取向和b取向的Tm,Ho:YAlO3晶体激光性能进行比较的实验研究。详细研究了Tm,Ho:YAlO3激光器的单波长和多波长运转。分别获得了a取向的Tm,Ho:YAlO3晶体在2119nm处890mW的最大输出功率和b取向的Tm,Ho:YAlO3晶体在2103nm处946mW的最大输出功率。两种晶体在输出功率和转换效率方面表现出非常相似的性能，只是b切割的Tm,Ho:YAP晶体展示出更多的多波长运转模式。
