制备了一种基于多层黑磷（BP）纳米片的紧凑型可饱和吸收镜（SAM），并成功地将其用作1.9 μm被动调Q Tm：雅普激光器的高效可饱和吸收体（SA）。在81kHz的脉冲重复频率下，获得了脉宽181ns、平均输出功率3.1W的调Q脉冲，脉冲能量为39.5 μJ，刷新了以往报道的调Q激光器的记录。此外，同时在1969和1979 nm的双波长Q开关操作已被观察到。结果表明多层BP纳米片作为SA在实现约2 μm的高效脉冲激光方面具有很大的潜力。
A compact saturable absorber mirror (SAM) based on multi-layered black phosphorus (BP) nanoplatelets was fabricated and successfully used as an efficient saturable absorber (SA) in a passively Q-switched Tm:YAP laser at 1.9 μm. With the BP SAM, Q-switched pulses with duration of 181 ns and average output power of 3.1 W were generated at a pulse repetition rate of 81 kHz, resulting in a pulse energy of 39.5 μJ, to the best of our knowledge, which is the record among the reports on BP SA-based Q-switched lasers. In addition, the simultaneous dual-wavelength Q-switched operation at both 1969 and 1979 nm has been observed. The results indicate the promising potential of multi-layered BP nanoplatelets as SAs for achieving efficient pulsed lasers at around 2 μm.
