摘要:
An analysis of the diffraction efficiency of photorefractive holograms in ferroelectric crystals is shown to provide a novel technique for determining the nature and magnitude of the equivalent electron drift field. For a Fe‐doped lithium niobate crystal (0.05% per mole) we find that the total field consists of an intensity‐independent internal field of 8.5 kV/cm and a photogenerated field given by the conversion factor 1.4 ×106V cm/W.
