摘要
本文研究了在泵浦光调制下的掺铒光纤激光器的混沌及其同步,给出了单环掺铒光纤激光器在泵浦条件下产生混沌的条件。利用混沌同步驱动法实现了激光器的混沌同步,通过计算最大条件Lyapunov指数随驱动强度的变化,我们确定了使两个激光器实现混沌同步的参数条件。
The chaos and chaotic synchronization of erbium - doped fiber ring laser with pump modulation have been investigated. The analysis of Lyapunov spectra shows fiber laser can be in chaos with proper parameter. On the other hand, it is realized for the chaotic synchronization of two lasers by a method of chaotic driving. The relationship between the maximum conditional Lyapunov exponents and the driving stiffness shows the parameter conditions for realizing chaotic synchronization.
