Abstract
The depletion efficiencies and their corresponding constant times are inves tigated in four differently doped barium titanate crystals at the near-infr ared wavelength of 854 nm. It is shown that the rhodium-doped crystal offer s the best results. Satisfactory motion tracking and edge enhancement are d emonstrated with an optical photorefractive novelty filter.
