我们确定了低频波动的各种物理机制，当半导体激光器在接近其孤立激光阈值时受到适度的光反馈时，就会发生低频波动。在试图达到通常是稳定的最大增益模式时，系统形成短的锁模脉冲。在脉冲之间可能发生模式滑移，通常是在最大增益方向上。不可避免的是，轨道太靠近许多鞍点中的一个，这将把系统带回孤立的激光状态。>；
We identify the various physical mechanisms in low frequency fluctuations, which occur when a semiconductor laser is subject to moderate optical feedback while operating close to its solitary laser threshold. In attempting to reach the maximum gain mode, which often is stable, the system forms short mode-locked pulses. In between pulses mode-slipping can occur, generally in the direction of maximum gain. Inevitably, the trajectory passes too close to one of the many saddle points, which will take the system back to the solitary laser state. >
