Abstract

The light stimulated anomalous self-blocking of all-optical poling process is observed. During investigation the big selfdecrease of light intensity of the generated signals of photo-induced second-harmonic generation has been detected in the region of high values of the induced electric field. The appeared self-decrease of light intensity blocks the process of the writing of the grating of nonlinear second-order susceptibility and leads to the restriction of the maximum value of photo-induced second-harmonic generation. Some properties of the observed phenomenon have been studied and the possible mechanisms of the dynamics of processes are discussed.
