为了研究双环掺铒光纤激光器的动力学特性，提出采用分立元件设计模拟电路并实现其混沌行为。根据系统的动力学方程，经过相应的系数变换，得到了对应的电路设计模型，并给出了电路仿真和硬件实验结果。实验通过调节电路中的可变电阻，可以将混沌控制到不同的周期轨道，与双环掺铒光纤激光器的动力学特性分析相同。研究结果表明，应用电路设计可以很好的模拟双环掺铒光纤激光器系统的动力学特性，而且理论分析与实验结果相一致。

In order to study the dynamics characteristic of dual-ring erbium-doped fiber lasers, the simulation method of designing a circuit using individual electronic components is proposed. This circuit is able to exhibit its chaotic behavior. Based on the equations of its dynamics system, the circuit simulation and hardware test results are obtained by transforming its coefficients and circuit design accordingly. By regulating the variable resistor of circuit in the experiment, the chaotic orbit could be adjusted with different orbiting periods. The result is consistent with dynamics analysis of erbium-doped fiber dual-ring laser. The applied circuit has good capability of simulating the dynamics of the dual-ring erbium-doped fiber lasers. In addition, the experiments show coherent results with the theoretical analysis.
