Self-induced diffraction grating storage in an azo-polymer film is investigated. From the in situ monitoring of self-backward and probe beam diffractions and atomic force microscopy images, the achievement of multistate storage of a single beam polarization and its relaxations are studied. The self-induced grating orientation follows the incident beam polarization direction.
