Abstract : A systematic investigation of tungsten bronze crystals for electro- optic and photorefractive applications has been carried out successfully. The Sr1-XBaXNb2O6 (SBN) and Ba2-XSrXK1-yNaYNb5o15 (BSKNN) system crystals were grown in optical quality with and without specific impurities whose purpose is to enhance photorefractive coupling and speed. Both SBN and BSKNN crystals appear to be excellent hosts for electro-optic applications, e.g., modulators, waveguides, and spatial light modulators (SLM) and photorefractive applications, e.g., phase conjugation, image processing, optical computing and laser hardening. For photorefractive applications cerium and chromium doping show the largest effects on photorefractive coupling and speed. Keywords: SBN, BSKNN, Czochralski, Tungsten bronze, Electro-optic properties, Photorefractive, Phase conjugation, Optical computing, Striations, Defects, Coupling, Sensitivity.
