摘要
设计了一种基于σ腔的非保偏光纤主动锁模光纤激光器。首先对激光器各个器件建立数学模型,并采用脉冲跟踪的方法对随机信号衍变成锁模脉冲信号的过程进行了仿真;然后搭建激光器系统,在仿真参数与实验参数一致的情况下,得到了基频为9.34 MHz,脉冲宽度980 ps的激光序列,实验与仿真的结果一致。
An actively mode-locked non-polarization fiber laser based on σ cavity was designed. Firstly mathematical model for every laser device was created, and the process that the random signal became mode locked pulse signal was simulated by using the pulse tracing method. Then the laser system was built. The fundamental frequency is 9.34 MHz and the pulse width is 980 ps when the simulation parameters are the same as the experimental parameters. Experimental results and simulation results match well.
