我们报告的结果全息研究的丙烯酸酯光聚合物系统包含一个可调液晶。我们证明，布拉格光栅可以形成在这个系统中，液晶大大提高了衍射效率。对于16.5wt%的液晶负载，我们已经观察到衍射效率接近100%。通过仔细控制液晶负载和快速后固化，我们获得了高衍射效率（> 80%）和窄角选择性（
We report on the results of holographic studies in an acrylate photopolymer system containing a nematic liquid crystal. We demonstrate that Bragg gratings can be formed in this system and that the liquid crystal greatly enhances the diffraction efficiency. For a liquid crystal loading of 16.5 wt %, we have observed diffraction efficiencies approaching 100 %. With careful control of liquid-crystal loading and rapid postcuring, we have obtained optically clear gratings of high diffraction efficiency (>80 %) and narrow angular selectivity (
