| 摘 要： | 对主动锁模光纤激光器的锁相环路进行了改进,提出一种通过使用"变带宽锁相环"来改善主动锁模光纤激光器稳定性的方法.该方法主要依据信号误差电压实时控制环路的带宽,使环路带宽随锁定信号的频率差动态改变,以达到快速锁定信号的目的,从而提高锁模光纤激光器输出光脉冲的频率稳定性.利用Matlab软件的Simulink功能模块对其实效性进行了仿真验证.结果表明,采用该方法,锁相环的捕捉性能和跟踪性能提高了,主动锁模光纤激光器的工作稳定性得到进一步改善.

| Abstract: | Phase-locked circuit in active mode-locked fiber laser was improved.A method was proposed to improve the stability of the mode-locked fiber laser by "transformable bandwidth phase-locked loop".With this method,loop circuit bandwidth can be real-time controlled by signal error voltage,urging bandwidth to change dynamically following margin between input and output frequency,making signal be locked quickly.Frequency stability of output optical impulse was improved thereby.And the practicality are simulated an... |
