17 August 1998 Photoinduced anisotropy and high-efficiency optical storage in azobenzene side-chain polymer

An amorphous tripolymer containing azo-side groups has been investigated in photoinduced anisotropy and polarization holographic recording. Measurements reveal that the effect of photobleaching process should be taken into account in explaining the experimental result using the mechanism of angular hoe burning or the angular redistribution of molecules in the azobenzene side-chain polymer film and that the polymer possesses large magnitude of photoinduced birefringence. A reversible polarization hologram with high efficiency is recorded with a CW 532 nm laser in this thin film at relatively low light intensity.
