Abstract

The holographic storage properties of Fe (0.03wt%. Fe₂O₃ ) : LiNbO₃ doped with Sc in different levels (0, 1, 2, 3 mol.%) have been investigated. The infrared spectrum of crystals shows that when Sc doping concentration in Fe: LiNbO₃ is over 3mol%, O-H vibration absorption peak of Sc (3 mol.%) ;Fe:LiNbO₃ is shifted to 3508 cm^-1, comparing with 3484 cm^-1 of crystals with lower Sc doping level. By the light spot deformation method the threshold intensity (wavelength 488nm) of Sc (3 mol.%) :Fe:LiNbO₃ is 3.3 × 10² W/cm², two orders of magnitude higher than that of Fe:LiNbO₃. The result of Infrared spectrum and optical damage resistance ability measurement shows that Sc threshold concentration in Fe:LiNbO₃ is about 3mol%. Holographic storage properties of crystals are determined using He-Ne laser with wavelength of 632.8 nm as light source by two-wave coupling method. It has been found that, in terms of holographic storage properties is best when the optimal doping concentration of Sc is 2 mol% among this crystal series.
