Nopal adhesive with natural pigment films for holographic recording

Abstract

In this work we present a preparation method of films for holographic recording. The no-toxic and cheap ingredients were used for film preparation, The films were prepared by mixing natural adhesive base on Nopal mucilage, which used as polymeric matrix, with a natural pigment as a photosensitizing agent, solution. Also, we show the experimental results of the first-order diffraction efficiency as a function of energy exposure from transmission diffraction holographic gratings, which were recorded in the films in real time.
