Abstract

We report the growth of doped Potassium Tantalate Niobate (KTN) crystals, and the characterization of their photorefractive properties m the paraelectric region. First the Top Seeded Solution Growth Method is reviewed and the growth process of a KTN:Cu, V crystal is described. Results of diffraction efficiency measurements of photorefractive gratings in these crystals at the paraelectric phase, are then presented. These experiments show high diffraction efficiencies, and indicate the possibility of amplitude modulation of the gratings by an external field. Results showing fixation of the gratings when the sample is close to the phase transition temperature are also described.
