摘　　要：研究了激光相位共轭波信号的同步传输问题。对激光相位共轭波的特性进行了理论分析。进一步通过耦合使两个激光相位共轭波系统建立关联。采用计算耦合系统的Lyapunov指数的方法,确定了信号达到同步传输时耦合强度的取值范围。结果显示,在Lyapunov指数小于零的区域任取耦合强度值,两个激光相位共轭波系统的同步输出均可以实现。Signal synchronization transmission of laser phase-conjugate wave is studied and its characteristics are theoretically analyzed.The connection between two laser phase-conjugate wave systems is established by coupling.The range of the coupling strength is obtained by identifying the Lyapunov exponent of the coupling systems.Experimental results show that the signal synchronization transmission can be realized in both coupling systems at the region with the Lyapunov exponent less than zero when the coupling strength is given as any value.
