We report on a new, to the best of our knowledge, technique enabling mitigation of the supermode noise (and timing jitter) in a soliton harmonically mode-locked (HML) fiber laser built on the nonlinear polarization evolution (NPE). An optical injection of an external continuous wave (CW) into the HML laser cavity results in an increase of the supermode noise suppression level (SSL) by a two-three order of magnitude for harmonics between 25th and 135th. The operation mechanism involves phase-locking between the injected light and soliton pulses and exhibits strong resonant dependence on the CW laser wavelength. Our findings offer important insights into the HML laser dynamics associated with an interaction between solitons and CW background in the laser cavity.
据我们所知，我们报道了一种新的技术，该技术能够减轻基于非线性偏振演化（NPE）的孤子谐波锁模（HML）光纤激光器中的超模噪声（以及定时抖动）。向HML激光腔中注入外部连续波（CW）光，可使第25至135次谐波的超模噪声抑制水平（SSL）提高两到三个数量级。其运行机制涉及注入光与孤子脉冲之间的锁相，并表现出对连续波激光波长的强烈共振依赖性。我们的研究结果为与激光腔中孤子和连续波背景之间相互作用相关的HML激光动力学提供了重要见解。
