We study the exfoliation of ultrathin ReS2 nanosheets from the prepared ReS2 powder and their application to Q-switched Er-doped fiber laser. XRD, Raman, and XPS spectra confirm the successful preparation of the layered ReS2. SEM images show that the obtained ReS2 sheets have lateral size below 200 nm. The thickness of the ReS2 nanosheets is smaller than 5 nm according to the AFM results. ReS2/PVA film is applied as a saturable absorber in an Er-doped Q-switched fiber laser, and a minimum pulse duration of 2.4 μs and an output power of 1.25 mW are obtained, indicating the potential application to Q-switched lasers.
