| 摘 要： | 研究了偶氮苯聚合物的光致各向异性光栅与表面光栅．实验结果表明短时间写入的光栅与光致各向异性有关，可以用任意偏振的单束光部分擦除．长时间写入的光栅属于表面光栅，不可擦除．它是由分子链团积引起的，分子链团积的动力来源于偶氮苯聚合物的光致异构．

| Abstract: | Optically induced anisotropy gratings and surface gratings on azobenzene polymer films are studied. It is shown that short time recorded gratings are resulted from light induced anisotropy,which can be erased by a single beam with any polarization. Long time recorded gratings are the surface gratings related to molecular accumulation caused by light induced isomerization and they cannot be erased by light. |
