Abstract
The formation of spontaneous gratings induced by a polarized laser beam in thin photosensitive AgCl waveguide films, doped by Ag, was studied by means of small-angle scattering. It is shown that small-angle scattering is determined by the domain structure of the spontaneous gratings and arises because of the re-emission of waveguide modes by neighbouring domains. The instability and reorganization of the gratings have been found and studied upon the change of the azimuth of the laser beam polarization.
