Holographic Image Storage in Eu(3+)-Doped Alkali-Aluminosilicate Glasses

Abstract

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. AUTHOR(S) ON REPRINT PERFORMING ORGANIZATION NAMES(S) AND ADDRESS(ES)Oklahoma State University Clear holographic images were stored using a total writing power of 5 mW and an exposure time of 20 s. In addition, clear holograms were recorded using an exposure time of 200 ms when 100 mW of the writing power was used. The exposure time and the writing power required for obtaining clear holographic images are dependent on the Eu 3+ concentration.
