We describe passively Q -switched Er:LuAG laser characteristics at 1.65 μ m 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 μ s was gained with the pulse repetition frequency of 34.2 kHz and the calculated peak power of 4.13 W.
