Selective page-addressable fixing of volume holograms in Sr(0.75)Ba(0.25)Nb(2)O(6) crystals.
We demonstrate selective fixing of volume holograms in photorefractive media. Each holographic page may be fixed individually and overwritten without destroying the other fixed pages. We present experimental results describing this process in Cr-doped Sr(0.75)Ba(0.25)Nb(2)O(6) at room temperature, with hologram lifetimes exceeding 100 days during continuous readout with an intense beam (1 W/cm(2)).
