“…Mode-locked fiber lasers have been arousing the extensive interest of many researchers due to their value in a variety of applications in the fields of basic science, fiber telecommunications, industrial materials processing, precise optical metrology, biomedical imaging, and others [1,2,3,4,5,6,7,8,9,10]. Currently, there are normally two strategies, actively mode-locked and passively mode-locked technologies, that are employed to realize the mode-locked operation in a fiber laser.…”
