摘要
对空间上相互耦合的两台非全同固体激光器的动力学行为进行了分析。当两台激光器的抽运受到调制而每台激光器的损失不同时 ,两台激光器输出的强度会出现周期性运动、混沌同步和失去同步的情况。激光中混沌同步的发生 ,同两台激光器之间的耦合程度有关。当耦合较强时发生周期性运动 ,耦合适中时处于混沌状态 ,在特定条件下产生混沌同步 ,而耦合较小时 ,两台激光器的振荡就相对独立。
The dynamical properties of two spatial coupled, non-identical solid state lasers are analyzed. When both of the lasers are pump-modulated with different losses, the output intensities of the two lasers show periodic motion, chaotic motion, chaotic synchronization and loss of synchronization. The occurrence of synchronization of chaotic lasers is related to the coupling between the two lasers. When the coupling is strong, the periodic motion occurs. For intermediate coupling, there appears chaotic motion. Chaotic synchronization may occur under certain condition. When the coupling is weak, the two lasers oscillate almost independently.
