光纤中超连续脉冲的频谱展宽

Spectrum widening and multi-wavelength output of supercontinuum pulse in fiber

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超连续脉冲进行了实验研究,成功实现了输出脉冲的频谱展宽。实验也发现,制约这个实验结果的主要因素是光纤激光器的输出脉冲的稳定性不够和功率不高。

For producing multi-wavelength Ultra-fast short pulse source of high-repetition frequency, Supercontinuum（SC） pulse generation in a conwentional dispersion shifted fiber（DSF） pumped by mode-locked Erbium-doped fiber laser is studied experimentally.The better laser pulse based on this source was obtained in the experiment,which carry out extending of the pulse bandwidth.And the experiment also demonstrates that the most important factor of this experimentation is the steady and high power laser pulse.
