Abstract

The optical nonlinearity and multiple holographic storage using azo side-chain polymer are investigated using degenerate four-wave mixing and polarized pump-probe laser method. The He-Ne excitation laser wavelength is located at the tail end of the absorption peak of the sample. This material shows high grating diffraction efficiency and promises information storage capability using weak absorption. The diffraction efficiency of the grating is up to the order of 10 -2. The effect of input beam polarization planes on grating is studied.
