摘　　要：研究了驱动场对非简并光学参变振荡器动力学行为的影响,通过计算系统的李雅普诺夫(Lyapunov)指数,发现当驱动场变化时,系统会出现定态、周期态、混沌态和超混沌态,并得到与各状态相应的驱动场取值范围。基于相图、Lyapunov指数谱和时间序列图的数值模拟也证实了计算结果,为进一步研究该系统的混沌反控制奠定了基础。The influence of driving field on dynamics characteristic in nondegenerate optical parametric oscillator（NOPO） is investigated.The Lyapunov exponents of nondegenerate optical parametric oscillator system are calculated,and also the steady state,periodic state,chaotic state and the hyperchaotic state with certain system parameters are obtained.The simulation results based on the Lyapunov exponent spectrum,phase diagrams as well as time series confirm our calculations.The results will be used in studying the anti-control of the nondegenerate optical parametric oscillator system.
