| Abstract: | Based on the principle of volume holographic storage in crystal, a compact volume holographic data storage system was designed with diode pumped solid state laser instead of the huge ionized argon laser More than 1500 high resolution holograms were stored and retrieved with the same diffraction efficiency by this system, resulting in a demonstrated volume density of 1 1Gbit/cm 3 and large data storage of 1 4Gbit The experiment results are presented |
