| Abstract: | The characterization of photoinduced birefringence in a new kind of the azobenzerie doped polymer film was studied by varying the intensity of the exciting beam and the angle 9 between the direction of polarization of exciting beam and probe beam. The experimental results showed that the new polymer film has a good characterization for optical storage with the conditions of low exciting beam intensity. The qualitative explanation to the experimental phenomena was also given. |
