Presents the study on characterization and mechanism of real time polarization holographic storage in acceptor donor azobenzene derivatives doped in polymethyl methacrylate film by degenerate four wave mixing, including time properties of grating dependence of the incident beam polarization states, and comparing the storage capability of the materials with azobenzene molecular configuration and concludes that the materials have highly sensitive third order nonlinearity and real time holographic storage ability which mainly result from the azobenzene molecular reorientation in photoinduced cis trans isomerization in low power.
