摘　　要：介绍了δ腔型SESAM启动锁模的全保偏掺Er光纤激光器重复频率锁定技术的原理和应用背景,并设计了一套可以快速实现SESAM锁模全保偏掺Er光纤激光器重复频率锁定的实验装置,最终将激光器的重复频率锁定到氢原子钟上,使得SESAM锁模全保偏掺Er光纤激光器的重复频率具有和氢原子钟同样的稳定度;对锁定前和锁定后重复频率进行了一定时长的数据采集,使用计算重复频率Allan方差的方法对全保偏掺Er光纤激光器的重复频率稳定度进行了量化,并对激光器锁定前后的重复频率进行了对比。通过比较可知,锁定后重复频率的稳定度比锁定前至少提高四个数量级。The principle of repetition rate locking technology and the application background of a 8 cavity SESAM mode-locked all polariza-tion maintaining Er-doped fiber laser is introduced and a set of experiment device which can quickly lock the repetition rate of SESAM mode- locked all polarization maintaining Er-doped fiber laser is designed. The locking device will finally lock the repetition frequency of laser to the hy-drogen maser, so that the stability of the repetition frequency of the fiber laser is the same as the hydrogen maser. The repetition rate stability of the all polarization maintaining Er-doped fiber laser is quantized by using the method of calculating repeated frequency Allan variance. And the stability of repetition rate is compared between the locked laser and the unlocked laser. By comparison, the stability of the repetition rate after loc-king is at least four orders of magnitude higher than that before locking.
