Passively Q-Switched Laser at 1.3 μm With Few-Layered MoS2 Saturable Absorber

Solid-state passively Q-switched Nd:LuAG laser at 1.3 μm with few layered MoS 2 as saturable absorber has been experimentally realized and demonstrated. The shortest pulse width of 188 ns and pulse repetition rate of 73 kHz were obtained. The experimental results verified the broadband saturable absorption characteristics of MoS 2 and indicated its ability to generate short pulses.
