摘　　要：提出一种用脉冲反馈法控制混沌的双环掺铒光纤激光器系统的方法.给出了控制的具体方案,并进行了数值研究.结果表明,只要选择合适的脉冲周期和耦合强度,就可以把处于混沌状态的双环掺铒光纤激光器成功的控制到不同的周期状态.文章还分析了噪声的影响并对控制结果作了讨论.This paper present a method of controlling chaotic Erbium-doped fiber dual-ring laser by chaotic pulse feedback to nonlinear system. The method is researched numerically and given concrete scheme. If pulse period and coupled stiffness are proper, the results show that a chaotic Erbium-doped fiber dual-ring laser can be successfully controlled into different periodic states. The effect of noise is considered and the control results are discussed .
