对均匀加宽激光器的动力学方程进行了修正。考虑光场随空间演化的效应, 得到修正后的均匀加宽激光器的动力学方程。进一步计算系统的最大Lyapunov指数随参量的演化关系, 发现存在Lyapunov指数大于零的参数区域。在此区域内, 系统呈现丰富的时空混沌行为。

The dynamic equation of the homogeneously broadened laser is modified. The dynamic equation of the modified homogeneously broadened laser is obtained by considering the effect of the spatial evolution of the optical field. The evolution with the parameter of the maximum Lyapunov exponent of the system is calculated. And the parameter region of the Lyapunov exponent greater than zero is found. In this region, the system shows rich spatiotemporal chaos behaviors.
