Transition from hyper-chaotic state to quasi-steady state in a spailally distributed nonlinear system

The dynamic characteristic in a spatially distributed nonlinear system, a subset of lasers in an array of coupled lasers, has been studied and analysed numerically. The evolution, with the increasing coupling strength, from stable quiescent state to chaotic state, to hyper-chaotic state and, back to quasi-steady state has been observed in this system.
