Abstract
We investigate the physics of a novel nonlinear system, feedback controlled photorefractive beam coupling. Inertia of the electronic feedback is found to be an element crucial for permanent operation of this system. Theoretic ally and experimentally we have found a wealth of periodic and quasi-period ic regimes for observable characteristics of the feedback controlled wave c oupling. A good qualitative agreement between theory and experiment is obta ined for LiNbO3 crystals. (C) 2001 Elsevier Science B.V. All rights reserve d.
