Control and synchronization of phase-conjugate wave spatiotemporal chaos system driven by CO2 laser

Abstract

Taking an one-dimensional coupled map lattice as an object, the characteristics of phase-conjugate wave spatiotemporal chaos system are investigated. Based on the Lyapunov stable theorem, the control of phase-conjugate wave spatiotemporal chaos system is achieved, and the multiple phase-conjugate wave spatiotemporal chaos system is driven into the parallel synchronization by the CO2 laser through choosing the coupling parameter. Numerical simulation results show that the coupling parameter has influence on the control and the synchronization speed of the phase-conjugation wave spatiotemporal chaos system. The greater the coupling parameter, the shorter the synchronization timeis.
