Holographic Storage Properties of Zn:Fe:LiNbO3 Crystals
|
Abstract:
Zn(1mol%):Fe:LiNbO3,Zn(4mol%):Fe:LiNbO3,Zn(7mol%):Fe:LiNbO3 crystals were grown by the Czochcalski method. In Zn:Fe:LN crystals, with the increasing of the doped concentration of Zn2+,the photo scattering resistance ability increased. The photo scattering resistance ability of Zn(7mol%):Fe:LN is over two orders of magnitude higher than that of Fe:LN. Measurement of the diffraction efficiency and the response time of Zn:Fe:LN crystals were performed.The holographic associated storage experiment were carried on by usingZn(7mol%):Fe:LN as a storage element and Zn(4mol%):Fe:LN as a phase conjugate mirror. The high quality, clear, integrated and low-moise pictures were obtained.The mechanism of holographic storage of Zn:Fe:LN crystals were investigated.Zn(4mol%):Fe:LN has the best quality in the holographic storage.
