Localized holographic recording in doubly doped lithium niobate


Persistent holograms are recorded locally with red light in a LiNbO>3 crystal doped with Mg and Fe. Selective erasure is realized by use of a focused UV sensitizing light. We demonstrate the recording of 50 localized images as well as selective erasure in a 4 mm × 4 mm × 4 mm crystal. A comparison of the total recording time for M holograms obtained with the conventional distributed-volume recording and the localized methods is presented.
