Paper Abstract

The temporary evolution of spontaneous gratings (SG), induced by a linearly polarized single laser beam ((lambda) r equals 632.8 nm and 441.6 nm) in thin AgCl-Ag films, is studied. It is found that the period of the gratings increases (decreases) as the laser exposition at 632.8 nm (441.6 nm) increases. This effect was explained by a generation of SG on waveguide modes scattered in films and by an existence of a colloidal Ag absorption band at 500 nm in the initial AgCl-Ag films. Percolation effects were found in the dependence of the halfwidth of diffraction reflexes on the exposition.
