Abstract
Holograms recorded under suitable conditions in photorefractive BaTiO3 exhibit an unusual dark build-up. The diffraction efficiency increase s by some orders of magnitude after the recording beams are switched o ff, and then steadily decreases afterwards. An interpretation of this effect in terms of a two-center charge transport model is given.
