We experimentally demonstrate a wavelength-switchable noise-like pulse (NLP) with modulation sidebands in an erbium-doped mode-locked fiber laser. The central wavelength of NLPs can be switched from 1530.2 to 1558.8 nm due to the birefringence filtering effect based on nonlinear polarization rotation. The corresponding pulse durations are 656 and 613 fs, respectively. As the total pump power increases to 700 mW, the modulation sidebands of NLPs can be observed by adjusting the polarization controller appropriately. The formation of modulation sidebands is caused by cross-phase modulation-induced modulation instability.

在掺fiber光纤激光器中观察到波长可切换的类似噪声的脉冲和调制边带

我们通过实验证明了掺an锁模光纤激光器中具有调制边带的波长可切换的噪声状脉冲（NLP）。由于基于非线性偏振旋转的双折射滤波效果，NLP的中心波长可以从1530.2 nm切换到1558.8 nm。相应的脉冲持续时间分别为656和613 fs。随着总泵浦功率增加到700 mW，可以通过适当调整偏振控制器来观察NLP的调制边带。调制边带的形成是由交叉相位调制引起的调制不稳定性引起的。
