摘　　要：基于锁模光纤激光器研究现状,及最新的全光纤化调Q方法,本文采用光纤的非线性偏转(NPR)效应进行自锁模,以及窄带滤波器与光纤布拉格光栅FBG进行调Q的技术。创新性的将这两种技术相连接以构建低重频、窄脉宽的全光纤激光器系统。通过所搭建的系统试验,最终得到脉宽在纳秒量级,脉冲间隔为80n(重频12.5MHz)左右的锁模脉冲。Based on the latest research progress of mode-locked fiber laser,as well as methods of Q-switch , a new laser system is proposed, NPR effect is for self mode locking,narrow band filter and FBG is for Q-switch. Combining the two methods, we build a system, then, through experiments we get mode-locked laser with pulse width in nanosecond, pulse interval in 80N.
