Abstract

Photoinduced periodic susceptibility formed in various isotropic media is promising in the future for possible practical applications in different areas of laser physics and photonics, in particular, for creation of the small-scale converters of light signals. The basic tasks of the investigations are to receive the samples not only with high efficiencies of the radiations conversions inside the inserted periodical susceptibility, but also with a long lifetime and stability to various kinds of influences. In this report we present the results of the investigations of the external red-light action on photoinduced susceptibility. The decay of the susceptibility under the action of the various intensities of red-light illumination is observed and the optimal conditions for sufficiently longtime stability are discussed.
