能同时产生不同频率脉冲信号的双波长主动锁模光纤激光器
Different Repetition Rate Optical Pulses Generation in Dual-Wavelength Actively Mode-Locked Fiber Ring Laser
摘要
用两只光纤光栅(FBG)作波长选择器件,实现了一种能同时输出两个不同重复频率的光脉冲序列的双波长主动锁模环形腔光纤激光器.通过调整外加调制信号的频率,使其中一个波长工作在谐波锁模状态,另一个波长工作在有理数谐波锁模状态.实验在2 GHz和2.5 GHz的调制频率下都成功地获得了双波长且重复频率不同的光脉冲序列,脉冲宽度分别约为60 ps和45 ps.
Abstract
A simple configuration for dual wavelength operation of actively mode locked fiber ring laser with fiber gratings is proposed. Simultaneously mode locked operation with two wavelengths,which one operates on harmonic mode locked status and the other operates on rational haronic mode locked status, is experimentally demonstrated.
