Experimental study demonstrates a high-damage-threshold molybdenum disulfide glass absorber reaching 3.22 W output in an Nd:YAG laser, indicating viability for high-power pulsed photonics.
In recent years, many different kinds of nonlinear optical materials have been applied to passively Q-switched solid-state lasers. However, the average output powers of these lasers are typically limited to 1 W due to the low damage threshold of the materials. In this study, a molybdenum-disulfide-doped glass-composite absorber was synthesized using the sol–gel method and spin-coating technique. The optical damage threshold of the absorber reached 3.17 J/cm 2 . Saturation intensity, modulation depth, and nonsaturable loss are 9.35 MW/cm 2, 8.41%, and 9.14%, respectively. After inserting the absorber into a linear Nd:YAG laser cavity, the maximum average output power (3.22 W) and stable Q-switched laser pulses duration (132 ns) were obtained.
