Deskripsi

We describe passively Q-switched Er:LuAG laser characteristics at 1.65 &#x03BC;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 &#x03BC; s was attained with the pulse repetition frequency of 41.6 kHz for the MoS<sub>2</sub> saturable absorber, resulting in the highest peak power of 4.33 W. For the WS<sub>2</sub> saturable absorber, a minimum pulse of 1.6 &#x03BC;s was gained with the pulse repetition frequency of 34.2 kHz and the calculated peak power of 4.13 W.
