混沌是在确定性系统中产生貌似随机的不规则运动, 这种非周期运动对初始条件极其敏感。激光混沌研究是混沌理论研究的重要组成部分。介绍了Ikeda激光系统模型。包括模型的建立、动力学方程以及相应的系统特性等。利用MATLAB程序仿真模拟系统的状态变量随参数演化的分岔图以及Lyapunov指数图。并结合仿真模拟得到的图像, 对系统特性进行了简单的分析与讨论。

Chaos is a kind of seemingly random irregular movement arising in a certain system, which is extremely sensitive to initial conditions. Laser chaos is an important part in the reserach of chaos theory. The Ikeda laser system model is introduced, which includes the establishment of the dynamic model, dynamic equation and the corresponding characteristics of the system. The Bifurcation and Lyapunov exponent maps are simulated by MATLAB. And the characteristics of the system are analyzed and discussed with simulation images.
