METHODS FOR IMPROVING PERFORMANCE OF HOLOGRAPHIC GLASSES

摘要

The improvement of the performance of holographic glasses with recorded holograms as measured by a figure of merit of the holographic glasses is disclosed. The improvement in the figure of merit of the holographic glasses is obtained at least in part with the addition of arsenic in the formation of the holographic glasses. The presence of arsenic increases the figure of merit as measured at a wavelength of interest of a holographic glass with a recorded hologram as compared to a holographic glass with a recorded hologram that does not contain arsenic.

主权项

1. A photorefractive, holographic, silicate glass comprising silver, bromine, fluorine, an oxide or cerium, and an oxide of arsenic, wherein the glass has a hologram recorded therein, and wherein the hologram is formed by changes in index of refraction within the glass.
