The holmium-doped calcium fluoride (Ho:CaF(2)) crystal was shown to be an effective solid-state saturable-absorber Q-switch for a flash-lamp-pumped Tm,Cr:Y(3)Al(5)O(12) laser at 2.017 µm. With a 1-cm-thick Ho(0.5%),Er(5%):CaP(2) saturable absorber and a 6.3% output coupler, a single Q-switched laser pulse of 51 mJ in energy and 60 ns in duration was obtained at a flash-lamp input energy of 85 J. With a 14.6% output coupler, a typical Q-switched laser pulse of 84 mJ and 82 ns was observed.
掺钬氟化钙（Ho:CaF₂）晶体被证明是一种用于闪光灯泵浦的Tm,Cr:Y₃Al₅O₁₂激光器（波长为2.017 µm）的有效固态可饱和吸收体调Q开关。使用厚度为1 cm的Ho(0.5%)，Er(5%):CaP₂可饱和吸收体和6.3%的输出耦合器，在闪光灯输入能量为85 J时，获得了能量为51 mJ、持续时间为60 ns的单个调Q激光脉冲。使用14.6%的输出耦合器时，观察到典型的调Q激光脉冲能量为84 mJ、持续时间为82 ns。
