In this paper, the optical storage properties of polyvinyl alcohol film doped with methyl red dyes were studied,where the dynamic curves of grating growth and decay were measured by using the writing light of 532nm and the reading light of 632.8nm.

• 用 2倍频小型 YAG激光 ( 53 2 nm)作为写入光和擦除光 ；用 He-Ne激光器 62 3 .；8nm线作为读出光；用 CCD作为探测器；研究了不同写入光功率下；甲基红 /聚乙烯醇 ( MR/PVA)薄膜光栅生长的动力学过程和不同擦除光功率下；光栅擦除的动力学过程
