Notes:
In this article, we have studied experimentally the threshold effect of incident light intensity for the photorefractive light-induced scattering and signal beam amplification in doped LiNbO3 crystals. Our results show that the signal beam can be most effectively amplified for a specific pump light intensity when the threshold effect of incident light intensity for photorefractive light-induced scattering is taken into account in doped LiNbO3 crystals. Doping the LiNbO3 crystal with suitable concentration of Fe and damage-resistant dopants will provide an effective way to control the photorefractive properties of LiNbO3 crystal. We demonstrated the advantage of the fanning-noise-free double-doped photorefractive LiNbO3 crystals for three-dimensional storage. This method to suppress the fanning noise is very simple and convenient to practice. © 2000 American Institute of Physics.
