Study of reflection gratings recorded in polyvinyl alcohol/acrylamide-based photopolymer

High-spatial-frequency fringes associated with reflection holographic optical elements are difficult to obtain with currently available recording materials. In this work, holographic reflection gratings were stored in a polyvinyl alcohol/acrylamide photopolymer. This material is formed of acrylamide photopolymer, which is considered interesting material for optical storage applications such as holographic memories. The experimental procedure for examining the high-spatial-frequency response of this material is explained, and the experimental results obtained are presented. With the aim of obtaining the best results, the performance of different material compositions is compared.This work was supported by the Ministerio de Ciencia e Innovación (Spain) under projects FIS2008-05856-C02-01 and FIS2008-05856-C02-02 and by the Generalitat Valenciana under projects ACOMP/2009/160 and ACOMP/ 2009/150
