Abstract

Multiwavelength lasing in the random distributed feedback fiber laser is demonstrated by employing an all fiber Lyot filter. Stable multiwavelength generation is obtained, with each line exhibiting sub-nanometer line-widths. A flat power distribution over multiple lines is obtained, which indicates that the power between lines is redistributed in nonlinear mixing processes. The multiwavelength generation is observed both in first and second Stokes waves.

摘要

通过采用全光纤利奥滤光器，在随机分布反馈光纤激光器中实现了多波长激光发射。获得了稳定的多波长输出，每条谱线的线宽均小于1纳米。各谱线的功率分布较为平坦，这表明各谱线之间的功率在非线性混合过程中进行了重新分配。在一阶和二阶斯托克斯波中均观察到了多波长产生现象。
