We describe passively Q-switched Er:LuAG laser characteristics at 1.65 μm for the first time, with MoS2 and WS2 as the saturable absorber, respectively. The saturable absorbers were both prepared with the liquid phase exfoliation method. A shortest pulse width of 1.1 μ s was attained with the pulse repetition frequency of 41.6 kHz for the MoS2 saturable absorber, resulting in the highest peak power of 4.33 W. For the WS2 saturable absorber, a minimum pulse of 1.6 μs was gained with the pulse repetition frequency of 34.2 kHz and the calculated peak power of 4.13 W.
