Abstract: A molybdenum disulfide (MoS2) saturable absorber (SA) was
fabricated by vacuum filtration method and employed to achieve passively
mode-locked Nd3+:YVO4 laser. The optical properties of MoS2 were
systematically characterized and the modulation depth was measured to be
7%. Stable continuous-wave mode-locked (CWML) laser at 1064.2 nm was
realized with a pulse repetition frequency of 88.3 MHz and a pulse width of
12.7 ps. The maximum output power of 89 mW was obtained under an
incident pump power of 2.1 W. The single pulse energy and peak power
were calculated to be 1.0 nJ and 83.3 W, respectively.
