Abstract
In this work the results of experimental investigations of holographic grating formation in photopolymer HPPM-633 are presented. On the base of fitting of experimental dependence of kinetics of diffraction efficiency with the theoretical one the photopolymer parameters are determined and presented. The photopolymer parameters such as diffusion coefficient and rate of their changing, optical absorption coefficient and rate of their changing, polymerization time, parameters defining contribution of photopolymerization and diffusion in change of refraction index, have been determined for other samples of photopolymer. On the base of model and numerical simulation it has been shown influence of experimental record conditions on diffraction efficiency, optimal record time, angle and wavelength selectivity of photopolymer gratings. The results obtained enable to define the optimal record time and direction of modification of photopolymer composition and external record parameters for achievement of diffraction characteristics predefined.
