Paper Abstract

In this paper we report an experimental method to optimize diffraction efficiency and sensitivity of the grating in a photopolymer system using Real Time Infrared (RTIR) spectroscopy. Polymerization profiles were directly recorded, allowing a precise evaluation of the polymerization rate and the photosensitivity. The optimum chemical composition of the photopolymer system for recording high diffraction efficiency transmission gratings is experimentally obtained. Using the RTIR results and a photopolymerization-diffusion model we have further determined the basic kinetic and diffusion parameters of the photopolymer system.
