摘　　要：基于单模双环掺铒光纤激光器混沌反馈相移控制方法和物理模型,分别对两种单环反馈相移的物理模型作了讨论。利用耦合器将系统的输出量反馈到系统中,选取适当的反馈系数,并在反馈通道上加入相移控制器控制反馈光的相移,通过对反馈系数和反馈光相移的控制可以有效地控制激光输出的混沌态、稳定态和周期态。在此基础上,对激光器双环反馈相移控制方法作了详细分析,研究了反馈系数和反馈相移对单模双环掺铒光纤激光器激光混沌双环反馈相移控制模型的影响,并得到一定的规律。Two physical models of single-ring feedback phase-shift controlling chaos are discussed based on the method of chaos controlled by coupling-feedback phase-shift and its physical model.The coupler feeds the output back and the phase-shift controller controls the phase of feedback.Suitable feedback coefficient and apt feedback phase-shift can control the laser output into chaos state,stable state or periodic state effectively.Moreover,the paper analyzes the method of double-ring feedback phase-shift controlling chaos in detail,and the impact of feedback coefficient and feedback phase-shift on the model of double-ring is studied.
