Abstract

Chaos-control techniques have been successfully demonstrated to convert a chaotic motion to a regular motion in various laser systems. Especially, small periodic perturbation techniques[1] can be achieved easily to control chaos in a simple, open-loop experimental setup. Chaotic laser output is stabilized to one of the periodic orbits that exist in the bifurcation region before the transition to chaos by application of a small perturbation. Thus the period of the regular oscillation obtained as a result of chaos control strongly depends on the original structure of the chaotic attractors and on their bifurcation[2]. Therefore the chaotic oscillation cannot be stabilized to an arbitrary periodic pattern that does not exist in the bifurcation. In addition, the period of the stabilized oscillation is not predictable in this control technique.
