|Title:||Stabilized Selective Photorefractive Holographic Erasure|
|Author:||De Oliveira I.|
|Abstract:||We report the selective erasure of a previously recorded 100% diffraction efficiency grating in a photorefractive lithium niobate crystal. Both the recording and the selective erasure are carried out using self-stabilized holo-graphic recording techniques. The recording and the erasure are shown to be in excellent agreement with the proposed corresponding theoretical model. After erasure, a grating of less than 5% diffraction efficiency remains in place. Almost no sensible light scattering was detected.|
