The chaotic and hyper-chaotic synchronization of non-degenerate optical parametric oscillators are investigated. The chaotic and hyper-chaotic synchronization of two non-degenerate optical parametric oscillators are realized by using unidirectional coupling driving method. When driving system is in chaotic and hyper-chaotic state respectively, it is got the range of the coupling constant to achieve chaotic synchronization in different states by using the chart of maximum condition Lyapunov exponent spectrum. Besides, by using idle-wave, signal-wave and two-mode coupling different results are got. It is got that signal-wave coupling is better than idle coupling, and two-mode coupling can optimize the chaotic synchronization. The synchronization results are perfectly verified by phase diagram and time series charts of the systems.
