本文论证了使用二硒化铼（ReSe2）作为宽带被动调Q（PQS）铥固体激光器可饱和吸收体的可行性。在2μm短波长区域，采用Tm:YLF与ReSe2的组合，实现了1900nm左右多波长的PQS操作。获得了862 mw的最大平均输出功率、527.9 ns的最短脉冲宽度和54kHz的重复率。在2μm长波长区域，实现了2050nm左右的ReSe2基PQS多波长Tm:Y2O3激光器，最大平均输出功率为1.04W，最短脉冲宽度为727 ns，重复频率为106kHz。 ReSe2基脉冲激光器的输出性能在使用新兴二维材料作为SA的PQS铥固体激光器中具有竞争力，这表明ReSe2是一种有前途的2μm固体激光器宽带SA。
The feasibility of using rhenium diselenide (ReSe2) as the saturable absorber for the broadband passively Q-switched (PQS) thulium solid-state lasers was demonstrated in this paper. In the short wavelength of 2 μm region, the combination of Tm:YLF and ReSe2was used to achieve the PQS operation with multi-wavelength around 1900 nm. A maximum average output power of 862 mw, a shortest pulse width of 527.9 ns and a repetition rate of 54 kHz were obtained. In the long wavelength of 2 μm region, a ReSe2-based PQS multi-wavelength Tm:Y2O3laser around 2050 nm was realized, generating a maximum average output power of 1.04 W, a shortest pulse width of 727 ns and a repetition rate of 106 kHz. The output performance of the ReSe2-based pulsed laser is competitive among these PQS thulium solid-state lasers using the emerging two-dimensional materials as SAs, indicating that ReSe2is a promising broadband SA for the 2 μm solid-state lasers.
