| Abstract: | In this paper, a chaotic impulse synchronization is proposed by using opti-electronic feedback. The laser chaos dynamical equations are numerically calculated, and the different chaotic states are obserred by modulating the coefficient of feedback or impulse which realizes the control of chaotic dynamics. Then, the impulse synchronization equations are numerically calculated, and the simulation image of synchronization is plotted. Experiments show the scheme can achieve the chaotic synchronization. |
