exfoliation (LPE), and the nonlinear saturated absorption performance was
experimentally studied. The modulation depth and saturation intensity of the
prepared GeSe saturable absorber (SA) were 15% and 1.44 MW/cm</span><sup><span style=\"font-family:Verdana;\">2</span></sup><span style=\"font-family:Verdana;\">,
respectively. Us</span><span style=\"font-family:Verdana;\">ing the saturated absorption
characteristics of GeSe SA, a passively Q-switched </span><span style=\"font-family:Verdana;\">erbium-doped fiber laser was systematically
demonstrated. As the pump</span><span style=\"font-family:Verdana;\"> power increases, the pulse repetition
frequency increases from 22.8 kHz to 77.59 </span><span style=\"font-family:Verdana;\">kHz.
The shortest pulse duration is 1.51 ¦Ěs, and the corresponding pulse</span><span style=\"font-family:Verdana;\"> energy is 46.14 nJ. Experimental results show that GeSe nanosheets can be used
as high-efficiency SA in fiber lasers. Our results will provide a useful
reference for demonstrating pulsed fiber lasers based on GeSe equipment.</span></span></span></span>
