Abstract
The results of the observation of process of the photo-induced frequency doubling of light in germanium-silicate patterns are presented. During the investigation a big anomalous growth of the light absorption has been detected in the region of the high induced electric field. The absorption blocks the process of the writing of the grating of the nonlinear second-order susceptibility and leads to the self-disappearance of the frequency doubling. Some properties of the observed phenomenon have been studied in experiments and the possible mechanisms of the dynamics of the observed processes are discussed.
