We demonstrated an efficient MoS₂-based eye-safe passively Q-switched Nd:GGG laser under 880 nm LD pumping. The maximum average output power was about 1.05 W with a slope efficiency of about 7.0%. The maximum pulse repetition rate and the shortest pulse width were 365.5 kHz and 146 ns respectively. To the best of our knowledge, this work represented the MoS₂ firstly used as a saturable absorber (SA) in Q-switched Nd:GGG laser operating at 1.4 μm wavelength, which deepened the understanding of the Q-switched performance of MoS₂ in this spectral region.
