“…Most of them, however, are still impractical in a commercial system because of their complicated processes or low diffraction efficiency. On the other hand, some novel materials, such as periodic poled LiNbO 3 , 8,9 stoichiometric LiNbO 3 , 10,11 and doubly doped LiNbO 3 , 7,12 have been proposed to improve the holographic abilities of crystals. Although there are specific advantages by using these novel materials, the global holographic properties of these materials are always worse than those of general iron-doped LiNbO 3 .…”

Abstract. We recorded a hologram in a photorefractive LiNbO 3 : Fe crystal with a two-color recording technique in transmission geometry. The holographic recording involves a light with wavelength 633 nm for interference, and a light with wavelength 532 nm for exciting. The short wavelength light excites more charges so that the holographic recording is affected, and the storage capacity ͑M-number͒ and the sensitivity vary accordingly. We found that the optimized intensity ratio of the interference lights and the exciting light is between 50 and 60. In the optimized conditions, the M number and the sensitivity are enhanced by 43 and 35%, respectively. Because the crystal we used is a typical iron-doped LiNbO 3 crystal and the short wavelength exciting light source is inexpensive now, the proposed method is easy to be achieved in most holographic systems.

We analyze theoretically the photorefractive response of periodically poled lithium niobate ͑PPLN͒ taking into account spatial fluctuations of its domain structure. It is shown that these fluctuations strongly affect the amplitude of space-charge field in the limit of small photorefractive grating vectors. The behavior of the nonlinear response in this limit is controlled by the root-mean-square of the spatial fluctuations of the domain structure. In the limit of large grating vectors, the nonlinear response is not sensitive to deviations from the ideal periodic geometry. The results obtained can be useful for the interpretation of photorefractive experiments and the formulation of requirements for the fabrication of photorefractive PPLN samples.
