Abstract
A passively Q-switched mode-locked Nd: YAG laser with a reflective molybdenum disulfide (MoS2) saturable absorber (SA) was demonstrated. The MoS2 SA was made by spin-coating the MoS2 nanoplates onto a home-made silver mirror. The modulation depth of the MoS2 SA was measured to be 3.05%. We optimized the laser beam radii in the crystal and on the reflective silver mirror with MoS2 by accurately designing the oscillator cavity. Under an incident pump power of 11â¯W, we got the maximum average output power as high as 1.06â¯W with a repetition rate of 94.72â¯MHz. The experimental results validated the outstanding characteristics of MoS2 SA and its further amplification possibility in high power all-solid-state pulse lasers.
