Abstract
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.
