| Abstract: | The photoinduced birefringence and holographic storage in methyl orange dyes (MO) doped polyvinyl alcohol (PVA) films were reported.The relationship between the photoinduced birefringence and the dye content and pumping power were investigated by using the writing light of 532 nm and the reading light of 632.8nm.The holographic experiments were carried out in these media.The physical mechanism of the optical storage in MO/PVA was elucidated. |
| Keywords: | Methyl orange Photoisomerization Photoinduced birefringence Holographic storage |
