摘要：

Utilizing the saturable absorption characteristics of transition metal dichalcogenides (TMDs), a passively Q-switched 1066 nm laser based on a novel Nd:GdYNbO4 mixed crystal as well as a two-dimensional (2D) layered molybdenum disulfide (MoS2) and tungsten disulfide (WS2) was realized for the first time. The highest repetition rate, the shortest pulse width and maximum peak power were 172 kHz, 723 ns and 0.85 W for Nd:GdYNbO4/WS2 laser, respectively. The corresponding values for the Nd:GdYNbO4/MoS2 laser were 122 kHz, 532 ns and 1.63 W. Furthermore, it was found that WS2 required a lower excitation energy, while a MoS2 nanosheet exhibits a deeper modulation depth.
