Abstract
Photoinduced anisotropy and polarization holographic recording have been studied in an amorphous tripolymer containing azo-side groups. It is shown that diverse mechanisms should be invoked to explain the experimental results. The polymer possesses a large value of photoinduced birefringence (Δ n=7.8×10 −3). A reversible polarization hologram with high efficiency (19.3%) has been recorded with a CW 532 nm laser at relatively low light intensity in the thin polymer film.
