The novel two-dimensional (2D) elementary tellurium is currently of great interest in optoelectronic and photonic applications. In this contribution, 2D tellurium nanosheets were successfully created by using the liquid-phase exfoliation method. With the as-prepared tellurium nanosheets as the saturable absorber (SA), we realized a passively $ Q $Q-switched ${\rm Nd} \text:{{\rm YVO}_4}$Nd:YVO laser operating at 1342 nm with a pulse width of 947 ns and single pulse energy of 2.25 µJ. Our work indicated the tellurium SA could be an efficient $ Q $Q-switcher for a near-infrared solid-state laser.
新型二维（2D）单质碲目前在光电和光子应用中备受关注。在本研究中，通过液相剥离法成功制备了二维碲纳米片。以所制备的碲纳米片作为可饱和吸收体（SA），我们实现了一台被动调Q的Nd:YVO₄激光器，其工作波长为1342 nm，脉冲宽度为947 ns，单脉冲能量为2.25 μJ。我们的工作表明碲可饱和吸收体可以成为一种用于近红外固态激光器的高效调Q开关。
