提出了利用相互耦合法实现恒定泵浦场二次谐波系统混沌控制和同步的方法。利用相互耦合法，选择合适的耦合系数可以实现两个不同的初始条件下二次谐波系统的混沌周期态同步。数值计算结果表明，在一定的泵浦强度下，这两个二次谐波系统尽管初始条件不同，在确定的参数范围内，通过调整相互耦合系数，可以将两个系统从混沌状态控制到周期同步态。这种方法为实现多个二次谐波系统和高次谐波系统的混沌控制和同步打下了良好的基础，对混沌保密通信工作具有重要的意义。

A method for chaotic controlling and synchronization based on mutual coupling is proposed in the optical intensity.If suitable coupling parameter in two SHG systems which are in different initial conditions is used,chaotic periodic behaviors can be controlled by the method of mutual coupling.The simulation results show that two SHG systems can reach chaotic synchronization by the mutual coupling. Although they have different initial conditions,this method can realize chaotic controlling and synchroniza-tion in two SHG systems.It lays the foundation for realizing chaotic controlling and synchronization in sev-eral SHG systems and higher harmonic systems,and it is significant for chaotic secure communication problems.
