我们报告了非线性放大器环镜 (NALM) 锁模的 8 字形光纤激光器中类噪声脉冲的捕获。在实现类噪声矢量脉冲后，发现负责脉冲捕获的两个解析偏振分量的波长偏移对腔双折射非常敏感。通过适当旋转偏振控制器 (PC)，波长偏移可达 4.8 nm，这比传统孤子捕获的波长偏移要大得多。观察到的结果将为类噪声脉冲的基本物理及其在光纤激光器中的矢量特征提供一些线索。 (C) 2015年美国光学学会
We report on the trapping of noise-like pulse in a figure-eight fiber laser mode locked by nonlinear amplifier loop mirror (NALM). After achievement of noise-like vector pulse, it was found that the wavelength shift of the two resolved polarization components responsible for the pulse trapping was very sensitive to the cavity birefringence. By properly rotating the polarization controllers (PCs), the wavelength shift could be up to 4.8 nm, which is much larger than that of conventional soliton trapping. The observed results would shed some light on the fundamental physics of noise-like pulse as well as its vector features in fiber lasers. (C) 2015 Optical Society of America
