AbstractBy using the ultrasound-assisted liquid phase exfoliation method, Bi2Te3nanosheets are synthesized and deposited onto a quartz plate to form a kind of saturable absorber (SA), in which nonlinear absorption properties around 2 µm are analyzed with a home-made mode-locked laser. With the as-prepared Bi2Te3SA employed, a stable passively Q-switched all-solid-state 2 µm laser is successfully realized. Q-switched pulses with a maximum average output power of 2.03 W are generated under an output coupling of 5%, corresponding to the maximum single-pulse energy of 18.4 µJ and peak power of 23 W. The delivered shortest pulse duration and maximum repetition rate are 620 ns and 118 kHz under an output coupling of 2%, respectively. It is the first presentation of such Bi2Te3SA employed in a solid-state Q-switched crystalline laser at 2 µm, to the best of our knowledge. In comparison with other 2D materials suitable for pulsed 2 µm lasers, the saturable absorption performance of Bi2Te3SA is proved to be promising in generating high power and high-repetitionrate 2 µm laser pulses. © 2017 Chinese Laser Press.
