Passively Q-Switched Er:LuAG Laser at 1.65 μm Using MoS2 and WS2 Saturable Absorbers


We describe passively <italic>Q</italic>-switched Er:LuAG laser characteristics at 1.65 <italic>μ</italic>m for the first time, with MoS<sub>2</sub> and WS<sub>2</sub> as the saturable absorber, respectively. The saturable absorbers were both prepared with the liquid phase exfoliation method. A shortest pulse width of 1.1 <italic>μ </italic>s was attained… (More)
