摘要 介绍一种简单的以自激注入锁定方式、生成边模抑制比改善的、可调谐双波长超短光脉冲的实验系统.系统通过调整两个B ragg光纤光栅和光延迟线,可方便地调谐两个不同波长及其间距,从而获得双波长光脉冲输出.实验显示,在20.7nm的波长调谐范围内,可获得边模抑制比接近或高于30dB的双波长光脉冲输出.系统简单,且波长调谐方便. A simple self-seeding scheme was demonstrated for tunable dual-wavelength optical short pulse generation with enhanced sidemode suppression ratio. The two wavelengths and their separation can be tuned in a flexible manner by adjusting two fiber Bragg gratings and an optical delay line. The sidemode suppression ratio of the output pulses achieved is close to or better than 30 dB over the wavelength-tuning range of 20.7 nm. The system is simple and robust and convenient for dual-wavelength tuning.
