通过利用 CsPbCl3 量子点 (QD) 作为可饱和吸收体 (SA)，演示了一种被动 Q 开关紧凑型双波长 Er:SrF2 激光器，工作波长为 2729.73 nm 和 2747.2 nm。最大平均输出功率为190 mW，最短持续时间为510 ns，重复频率为45 kHz，相应的最大单脉冲能量和峰值功率分别为73.69 μJ和141.7 W。研究结果提出了一种高效的双波长激光源，并且卤素钙钛矿量子点有潜力在中红外脉冲固态激光器中用作优异的可饱和吸收体。
A passively Q-switched compact dual-wavelength Er: SrF2 laser, operating at a 2729.73 nm and 2747.2 nm wavelength, was demonstrated by utilizing CsPbCl3 quantum dots (QDs) as a saturable absorber (SA). The maximum average output power with the shortest duration of 510 ns and a repetition rate of 45 kHz was achieved at 190 mW, and the corresponding maximum single pulse energy and the peak power were 73.69 μJ and 141.7 W, respectively. The results present an efficient dual-wavelength laser source, and the halogen perovskite quantum dot has the potential to be employed as an excellent saturable absorber in mid-infrared pulsed solid-state lasers.
