Photoinduced orientation and recording of erasable holographic gratings in a new photoresponsive amorphous polymer containing azobenzene groups were studied. Using linearly polarized white light and Ar+ laser beam at 488 nm, orientation of azobenzene groups perpendicular to the polarization direction of the incident light was observed in polymer films. Holographic gratings with high diffraction efficiency were recorded by polarized Ar+ laser beams at 488 nm. These gratings were stable at room temperature. Writing of multiple gratings at the same spot on the polymer films also was investigated. The holographic gratings can be erased by heating the samples above the glass transition temperature and can be rewritten on the same spot. This was performed for fifty cycles.
