Wavelength-tunable pulsed fiber lasers have many potential applications in sensing, communications, spectroscopy, and medicine. Pulsed fiber lasers based on two-dimensional (2D) materials are easier and simpler to integrate into the laser cavity than those based on traditional mode-locked techniques such as nonlinear polarization rotation and semiconductor saturable absorber mirror. In this review, we discuss the principles and report on the current progress of wavelength-tunable pulsed fiber lasers based on graphene, graphene oxide (GO), topological insulators (TIs), transition metal dichalcogenides (TMDs), and black phosphorus (BP). Then, we discuss the mechanisms to achieve wavelength-tunable pulsed operation. Finally, an outlook about the development of tunable pulsed fiber lasers is presented in the perspectives.

波长可调脉冲光纤激光器在传感，通信，光谱学和医学中具有许多潜在的应用。与基于传统锁模技术（例如非线性偏振旋转和半导体可饱和吸收镜）的激光器相比，基于二维（2D）材料的脉冲光纤激光器更易于集成到激光腔中。在这篇综述中，我们讨论了基于石墨烯，氧化石墨烯（GO），拓扑绝缘体（TIs），过渡金属二卤化金属（TMDs）和黑磷（BP）的波长可调脉冲光纤激光器的最新进展并进行了报道。 。然后，我们讨论了实现波长可调脉冲操作的机制。最后，这些观点对可调谐脉冲光纤激光器的发展提出了展望。
