Abstract : Growth of barium sodium niobate crystals from twenty-five different compositions in the single phase, solid solution region of the ternary phase diagram is described. Correlations between color center formation, strain, phase-matching temperature and composition are made. Crystals grown from melts containing less than 48.5 mol percent niobium pentoxide are colorless. Results of extinction ratio measurements for crystals of one composition and SHG measurements for crystals of several compositions are given. (Author)
