Abstract

Suppression of laser chaos by means of a weak external periodic forcing has been demonstrated recently /1,2/. The mechanism of suppressing chaos was explained as that by application of an external periodic force, one of the unstable periodic orbits embedded in the chaotic attractor is stabilized. Suppression of chaos with this technique results in a chaotic laser lasing in a periodic state. In this paper we demonstrate experimentally that by means of an external chaotic forcing, the intrinsic chaotic dynamics of a single mode laser can be suppressed. After suppression of the intrinsic chaotic nature, although the laser output still looks chaotic, it is however completely controlled by the external forcing signal.
