Paper Abstract

Holographic volume gratings as diffractive elements have much practical and more potential applications, such as spatial filters, attenuators, modulators, imaging lenses and so on. The reflection volume gratings have more higher wavelength selectivity than transmission gratings and is more suitable for spectral selectors. A type of photosensitive-refractive glass, silicate glass doped with silver, cerium, fluorine, and bromine, was fabricated at our lab and the basic holographic performances of the PTR glass are experimental measured in this paper. Holographic volume grating were recorded in the photosensitive-refractive glass sample by exposured to the interference pattern of a He-Cd laser operating at 325nm and 442nm respectively. A feasible experimental strategy for readout this kind of grating by invisible or longer wavelength light is presented based on the theory of coupled waves.
