【摘要】 本文从简化的激光方程出发，引入周期调制，建立一理论模型。数值计算表明，在某一参数范围内，发现方程中存在倍周期分岔序列至混沌，理论与实验符合较好。更多还原

【Abstract】 By introducing a periodic modulation theortical model is formulated from the simplified laser equations.Numerical simulations show that within some various parameter regions there exists a sequence of double period bifurcations and that chaos phenomena appear in the equations.These results are in good agreement with the experimental data.更多还原
