研究了具有净法向色散的被动锁模光纤激光器中松散束缚孤子和类噪声脉冲的共存动力学。在NLP工作模式下，单孤子束的总脉冲数随泵浦功率的增加几乎呈线性增加，而平均脉冲间隔则相应减小。此外，在一个孤子束中，相邻孤子脉冲之间的脉冲间隔保持在几百皮秒的范围内，随着时间的变化，从左到右逐渐减小。此外，利用时间拉伸方法对孤子进行了实时观测，结果表明，在NLP操作下的每个松散束缚孤子实际上都是由强度随机的混沌波包组成的。这些结果将有助于深入理解超快光学中的非线性脉冲行为。(C)根据OSA开放获取出版协议的条款，2020年美国光学学会
We demonstrate the coexisting dynamics of loosely bound solitons and noise-like pulses (NLPs) in a passively mode-locked fiber laser with net-normal dispersion. The total pulse number of the single soliton bunch under the NLP operation regime almost increases linearly with increasing pump power, whereas the average pulse spacing decreases accordingly. Furthermore, pulse-to-pulse separation between adjacent soliton pulses in one soliton bunch keeps in the range of hundreds of picoseconds, which decreases from left to right with the change of time. Besides, the real-time observation has been performed by utilizing the time-stretch method, showing that each one of the loosely bound solitons on the NLP operation is actually composed of chaotic wave packets with random intensities. These findings obtained will facilitate the in-depth understanding of nonlinear pulse behaviors in ultrafast optics.
