Theoretical and experimental investigations on two-dimensional transition-metal dichalcogenides passively Q-switched/mode-locked fiber laser

脉冲光纤激光器不仅具备光纤激光器的优点，同时还可以实现瞬时的高峰值功率、大脉冲能量。脉冲调制技术主要分为两类：主动调Q/锁模和被动调Q/锁模。主动调Q/锁模的方法需要在谐振腔内插入一个调制器，往往还需要外部有源驱动，这样不仅仅增加了成本，还使激光系统的复杂程度增加。而相比于主动调Q/锁模的这些限制，被动调Q/锁模具有低成本、腔体结构紧凑、设计灵活等多样优点使得它备受关注。 被动调Q/锁模光纤激光器技术常用的方法是在激光腔内加入可饱和吸收体，但是传统的可饱和吸收体存在着许多不足，已经无法满足日益发展的光纤脉冲激光器的要求。二维硫化物过渡金属材料作为又一种新型的可饱和吸收体材料，受到广泛的关注和...Pulsed fiber laser not only has the advantage of fiber laser, but also can achieve the instantaneous high peak power, high pulse energy. The techniques of laser pulse generation can be mainly divided into two kinds:(1) actively Q-switched/mode-locked and (2) passively Q-switched/mode-locked. Active Q-switching/mode-locking technique usually needs to insert an active modulator into the resonator, a...学位：工程硕士院系专业：信息科学与技术学院_工程硕士(电子与通信工程)学号：2312012115288
