本文从实验和理论上研究了在聚甲基丙烯酸甲酯及其热稳定衍生物（丙烯酸共聚物）玻璃状聚合物存储材料中，通过二波混频写入菲醌的体相位光栅。最大衍射效率被认为是依赖于光栅周期。分子的再分布过程描述与一维扩散模型产生的光聚合物层中的非局部响应的存在，并相应的菲醌的非局部响应长度的实验发现。(C)2008年美国光学学会。
The development of volume phase gratings written by two-wave-mixing in glass-like polymer storage materials based on poly (methylmethacrylate) and its thermostable derivative (copolymer with acrylic acid) with distributed phenanthrenequinone is investigated experimentally and theoretically. The maximal diffraction efficiency is considered in dependence on the grating period. The redistribution processes of the molecules are described with a one-dimensional diffusion model yielding the existence of a non-local response in the photopolymer layer, and the corresponding non-local response length of phenanthrenequinone is found experimentally.
