摘要
对空间耦合的两台多模激光场的强度和相位的动力学行为进行了理论分析。当系统的损失受到调制时,在一定的参数范围内,两台激光输出的总强度之间会出现很好的混沌同步,两台激光的对应模式之间也出现相应的混沌同步,但不同模式之间则是完全的混沌状态,每台激光的各个模式强度之间存在模式竞争现象。每台激光场不同模式的相位和相位差之间出现有趣的关系,与强度的混沌同步存在一定的联系。
The dynamical properties of two spatially coupled multi-mode lasers are investigated theoretically. When the loss of the system is modulated, the total intensities of the two lasers show perfect chaotic synchronization within certain parameter range. The intensities of the corresponding modes also show chaotic synchronization. While for different modes, the intensities are totally chaotic. The intensities of the modes in the lasers show mode competition. The phase and phase difference in each mode show very interesting relations. There is some link between the chaotic synchronization of intensities and phases.
