针对因脉冲式光纤激光器的重复频率较低而无法进行高速率发射传输的问题，本文通过对脉冲式光纤激光器的L-PPM调制进行研究，找出一种可以有效提高脉冲式光纤激光器调制速率的方法。通过对能够影响到PPM调制速率的各种参数进行分析，找出一组最佳的参数进行实验。实验结果表明，L-PPM调制方式可以将重复频率为200K的脉冲式光纤激光器的传输速率提高到1.387Mbps。研究结果有利于脉冲式光纤激光器在通信中的应用。

Due to the lower repetition frequency of pulsed fiber laser, it cannot realize high rate transmission. In this paper,the L-PPM modulation on pulsed fiber laser is researched and a method that can effectively improving the mod-ulation rate of pulsed fiber laser is found. Through the analysis of variety parameters which should affect on the PPM modulation rate,a group of best parameters was found. Experimental results show that the L-PPM modulation can im-prove the transmission rate of the pulsed fiber laser whose repetition frequency is 200K to 1.387Mbps. The research re-sults are useful for the application of pulsed fiber laser in communication.
