论文摘要
我们研究了激光腔中的转式工艺，在激光腔中，往返时间比活性介质时间尺度大几个数量级。在这个长延迟中，可以在往返后往返的电磁场堆积。我们展示了从随机初始条件开始的连贯性如何降低。在上交的早期阶段，我们表明出现了动力掉落，持续了几次往返和种子深色孤子。这些后一个结构表现出混乱的动力学和发射辐射，可以根据空腔分散体导致整体湍流动力学。
We investigate the turn-on process in a laser cavity where the roundtrip time is several orders of magnitude greater than the active medium timescales. In this long delay limit the electromagnetic field build-up can be mapped experimentally roundtrip after roundtrip. We show how coherence settles down starting from a stochastic initial condition. In the early stages of the turn-on, we show that power drop-outs emerge, persist for several round-trips and seed dark solitons. These latter structures exhibit a chaotic dynamics and emit radiation that can lead to an overall turbulent dynamics depending on the cavity dispersion.
