In this work we present an experimental study of the hysteretic behavior of an Yb mode-locked fiber laser in a multi-pulsing regime. Our main focus is on the internal nonlinear transmission curve of the laser, which is fundamental to obtain the mode-locking regime. We have also observed hysteresis in the the temporal separation between dispersive bound solitons. These results have been interpreted in terms of the negative and positive feedback and the redistribution of the solitons energy.

锁模光纤激光器在多脉​​冲状态下传输曲线和孤子时间分离的滞后行为

在这项工作中，我们对 Yb 锁模光纤激光器在多脉​​冲状态下的滞后行为进行了实验研究。我们主要关注激光器的内部非线性传输曲线，这是获得锁模机制的基础。我们还观察到色散束缚孤子之间时间分离的滞后现象。这些结果已被解释为负反馈和正反馈以及孤子能量的重新分配。
