We report on the experimental observation of a type of parametric spectral sideband generation in a continuous wave (CW) fiber laser operating in the normal dispersion regime. The appearance of the sidebands is a threshold effect and their spectral shifts from the CW wavelength vary with the cavity length and CW power. We show that the sideband formation is induced by the periodic power variation of the light in the laser cavity.

单模光纤激光器中周期性功率变化引起边带不稳定性

我们报告在正常色散状态下运行的连续波（CW）光纤激光器中的一种参数光谱边带生成的实验观察。边带的出现是一个阈值效应，它们从CW波长的光谱偏移随腔长和CW功率而变化。我们表明边带形成是由激光腔中光的周期性功率变化引起的。
