Abstract: The chaos and chaotic synchronization of erbium-doped fiber ring laser with loss modulation were investigated. The analysis of the max Lyapunov shows fiber laser can be in chaos with proper parameters. On the other hand, the chaotic synchronization of two lasers is realized 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. Also, the influence of parameter mismatches on chaos synchronization was investigated.

Key words: fiber laser, chaos, chaotic synchronization, synchronization error
