Abstract

The ultrathin MoS,2, nanosheet dispersion saturable absorber is prepared by ultrasonic peeling method. The quartz cell is used as a container and insert into the flat-concave cavity of the Nd∶YAG laser. By adjusting the position of the resonant cavity mirror and increasing the pump power, the passive ,Q,-switched pulse output of the Nd∶YAG laser is successfully achieved. Experimental results show that when the pump power is 2.46 W, the laser starts ,Q,-switched operation. When the pump power is 14.55 W, the maximum pulse laser output power of 485 mW is achieved, the repetition frequency is 189.75 kHz, the pulse width is 1.2 μs, and the corresponding maximum pulse energy is 2.56 μJ. The results show that the ultrathin MoS ,2, aqueous solution is a saturable absorber material suitable for passive ,Q,-switching operation of 1 064 nm wavelength solid-state lasers.
