A passively Q-switched microsecond Er-doped fiber laser at 1532 nm wavelength was demonstrated by using a ReS2-based saturable absorber. The absorber was fabricated with ReS2 by exfoliating mechanically and transferred onto a fiber end. Stable Q-switched laser pulses were observed with the shortest pulse duration of 2.1 μs, the maximum average output power of 2.48 mW, and the pulse with energy up to 38 nJ. Our experimental results suggest that ReS2 is potential for a Q-switcher near 1.55 μm wavelength.
