摘要：
Rhenium disulfide (ReS2), one of the typical representatives of 2D layered transition metals dichalcogenide materials, has attracted widespread attention for its optical modulation properties in lasers. In this letter, a high-quality ReS2 nanosheet film-based saturable absorber (SA) was successfully prepared by a liquid phase exfoliation method and employed into a passively Q-switched Ho,Pr:LiLuF4 bulk laser operating at 2.95 mu m. The maximum output power of 103 mW was obtained with the shortest pulse duration of 676 ns and a repetition rate of 91.5 kHz, corresponding to the single pulse energy of 1.13 mu J and a pulse peak power of 1.67 W, respectively. The results indicate that ReS2 is a promising SA for mid-infrared pulse generation.
