摘　　要：单模激光Lorenz系统是一个典型的非线性模型,其本身能够呈现极其复杂和丰富的动力学行为,对其特性研究十分重要。在简介单模激光Lorenz系统模型,其中包括模型的建立、动力学方程以及相应的系统特性等相关内容的基础上,编制MATLAB程序,利用计算机仿真模拟不同参量下单模激光Lorenz系统的相图。并结合仿真模拟的图像,对单模激光系统在不同参量下的动力学行为进行简单的分析与讨论。结果表明,当系统参数大于分支点处的取值时,系统变为不稳定的,从而进入混沌状态。Single-mode laser Lorenz system is a typical nonlinear model, which shows extremely complex and rich dynamic behaviors. It is very important to the research on characteristics. Based on a brief introduction of single-mode laser Lorenz system, which including model establishment, dynamic equations and relative system characteristics, the program is programmed by Matlab software and the phase maps of single-mode laser Lorenz system with different pa-rameters is simulated by a computer. With simulated images, dynamic behaviors of the system are analyzed and dis-cussed. The results show that when the parameter of the system is more than the value of a branch point, the system be-comes unstable and thus enters into a chaotic state.
