Coupling and chaotic synchronization in two single mode lasers

对空间上相互耦合的两台单模固体激光器的动力学行为进行了分析 当其中一台激光的泵浦受到调制时 ,对于不同的参量 ,两台激光输出的强度会出现混沌同步和失去同步的情况 混沌激光的同步是否发生 ,同两台激光之间的耦合程度有关 当耦合较强时可能发生混沌同步 ,而耦合较小时 ,则失去混沌同步现象 ,当耦合进一步减小时 。

The dynamical properties of two spatially coupled solid state lasers are analyzed if the lasers are operated in a single mode state.When one of the lasers is pump modulated,the output intensities of the two lasers show chaotic synchronization and loss of synchronization for different parameters.The occurrence of synchronization of chaotic lasers is related to the coupling between the two lasers.When the coupling is strong ,chaotic synchronization may occur.While the coupling is weak ,the chaotic lasers may lose synchronization.When the coupling is reduced further,the two lasers oscillate independently.
