ABSTRACT:
A volume hologram is created by exposing a volume holographic optical storage medium comprising a doped optically transparent glass matrix having a scattering coefficient of less than 10.sup.-5 cm.sup.-1 to an interference pattern created by intersecting a spatially modulated object beam with a reference beam, the object beam and the reference beam each having a wavelength of less than about 300 nm. The glass matrix may be doped with any of the following: (1) nanocrystalline semiconductor particles and an activator, (2) an alkaline earth sulfide, Sm ions, and an additional dopant selected from the group consisting of Eu ions and Ce ions, (3) ZnS and an additional dopant selected from the group consisting of Pb ions, Cu ions, and Mn ions and (4) Cu or Ce ions.
