聚合物材料PMMA/DR1光漂白过程中折射率的变化
Index Change of PMMA/DR1 Film During Photo-Bleaching
摘要
用双光束扫描法研究了在488nm的Ar+激光照射下,聚合物材料PMMA/DR1的光漂白过程,为精确测量光漂白模型中的参数提供了一种简单实验方法.这对于今后用光漂白的方法制备光波导器件具有重要意义.
Abstract
The photo bleaching processes in a nonlinear optical polymer film used poly (methyl methacrylate) based dispersive red one (DR1/PMMA) side chain at 488 nm argon ion laser radiation was investigated. The index change of DR1/PMMA film was measured by two beam scan technique. It provides a simple method to determinate the parameters in bleaching model describing the photo bleaching processes of polymer.
