Paper Abstract

Photoinduced birefringence in the film made of our azobenzene copolymer was demonstrated using blue excitation laser beams and observed by a red probe laser beam. The birefringence values was obtained by polarimeter. The polarization state of the probe beam was changed by the photoinduced birefringent film when the polarization state is not agreed with the polarization state of the excitation laser beam. Then, a polarization component orthogonal to the polarization state of the incident probe beam was observed. Using the principle, an image pattern was recorded in the film using one-beam.
