Some aspects of synchronization and chaos in a coupled laser system

Some dynamical properties and synchronization are studied in a coupled system of solid state lasers without external modulation. It is observed that two different situations may arise – when the individual systems are operating in the stable region and when both of them are chaotic. In both the situations the coupling leads to a chaotic scenario. These two events are analysed with respect to the coupling parameter. The synchronization of two lasers is studied by using the notion of parameter variation, drive decomposable system and adaptive control mechanism.
