This is the authors' abstract. We don't add key points for this paper.
This paper describes the results of an investigation into techniques for obtaining erasure resistant holograms in electro-optic crystals. The most successful approach made use of thermally activated ionic drift during or after recording. The samples are heated for about 30 min at 100°C to obtain optically nonerasable holograms with as much as 50% diffraction efficiency in LiNbO3 or in doped Ba2NaNb5O15.
