摘要
研究了在 10 64nm处非线性吸收对有机聚合物材料PMMA/DR1光漂白的影响。实验结果表明 ,在较强的入射光作用下 ,由于双光子吸收的作用 ,使得PMMA/DR1发生光漂白 ,其折射率产生微小的变化 ,且随光漂白时间的增加而产生饱和。
The influence of the nonlinear absorption on the photobleaching of polymer PMMA/DR1 film is studied in this paper. The experimental results show that the photobleaching induced by the two-photon absorption at 1064nm wavelength can make the film's refractive index change, but this change will become saturated with the photobleaching time.
