SYNCHRONIZATION OF DYNAMIC CHAOS IN COUNTERPROPAGATING RING-LASER WAVES

Experimental and theoretical investigations were made of dynamic chaos in a solid-state ring laser with periodically modulated pumping. Sync hronised dynamic chaos in a bidirectional ring laser was demonstrated for the first time, Regions of existence of strange attractors of two types, synchronised and nonsynchronised, were found in the plane of th e system parameters (pump frequency and modulation depth). Competition between these attractors was discovered. The spectra of the Lyapunov exponents and the information dimensionality were calculated for the a ttractors of both types.
