Paper Abstract

Photopolymer materials are good materials for the recording of holographic optical elements (H.O.E's), as they are inexpensive and self-processing. Understanding the mechanisms present during the fabrication of gratings in these materials is crucial in enabling further developments. One such mechanism is the presence of an inhibition period at the start of grating growth during which the formation of polymer chains is suppressed. Some previous studies have indicated possible explanations for this effect and mathematical models have been proposed to approximate the observed behaviour. We have carried out a set of experiments with the specific aim of developing an improved understanding of this process. In this paper we discuss these experimental results and provide a theoretical model, which describes the inhibition process in our Acrylamide based photopolymer and predicts this behaviour under certain conditions.
