为了产生高重复频率的多波长短光脉冲,利用锁模掺铒光纤激光器作为抽运光源,对色散位移光纤中的脉冲光谱展宽进行了实验研究,成功地实现了45 nm超连续谱的产生,并滤波得到了多波长输出.实验还发现,光纤激光器的输出脉冲的稳定不够和功率不高是制约这个实验结果的主要因素.

In order to obtain multi-wavelength short pulse source with high-repetition frequency, supercontinuum (SC) spectrum generation in dispersion-shifted fiber (DSF) was experimentally investigated. In use of actively mode-locked Er-doped fiber laser as pump, supercontinuum with 40 nm width was obtained. And the experiment also demonstrated that the stability and power of the pump pulse are important factors for supercontinuum generation.
