Abstract
We analyze the nonlinear excitation of holographic gratings in a photo refractive crystal being subject to an alternating electric field and a stationary light interference pattern. The influence of the higher h armonics on the fundamental grating is illustrated for the case where a crystal of Bi12SiO20 is the recording medium. We analyze both the st eady state and the transient consequences of the higher harmonic excit ation. (C) 1998 Elsevier Science B.V. All rights reserved.
