Abstract

N, N-dimethyl-4-nitroaniline doping enables red-light holographic recording that was originally insensitive in thick phenanthrenequinone/poly(methyl methacrylate) photopolymer to have reasonable sensitivity. A volume hologram was recorded by a 647 nm laser with maximum diffraction efficiency of about 43% in a 2-mm-thick sample. A Bragg selectivity curve and an image hologram reconstruction are also demonstrated. These experimental results support recording material for volume holographic applications in an extended red spectral range.

摘要

N,N-二甲基-4-硝基苯胺掺杂使原本对厚菲醌/聚甲基丙烯酸甲酯光致聚合物不敏感的红光全息记录具有合理的灵敏度。通过 647nm 激光记录体积全息图，在 2mm 厚的样品中最大衍射效率约为 43%。还展示了布拉格选择性曲线和图像全息图重建。这些实验结果支持在扩展的红光光谱范围内用于体全息应用的记录材料。
