Abstract High quality oxide and fluoride single crystals for optical, piezoelectric and other applications have been grown by advanced crystal growth techniques. La3Nb0.5Ga5.5O14 and La3Ta0.5Ga5.5O14 piezoelectric single crystals of size and quality comparable to La3Ga5SiO14 (langasite), have been produced. The piezoelectric and device properties of the crystals were investigated. A search for new langasite-type materials was also performed. Growth conditions of (La,Sr)(Al,Ta)O3 and Ca8La2(PO4)6O2 single crystals are discussed. These crystals have excellent lattice matching with GaN, a promising material for optoelectronic devices. Promising optical micro-crystals—K3Li2Nb5O15, KNbO3 and Y3Al5O12—and new structural materials, Al2O3Y3Al5O12 eutectic fibers, have been grown by the micro-pulling-down (μ-PD) technique. The advantages of the μ-PD technique have been shown. Ce-doped fluoride single crystals—LiCaAlF6, LiYF4 and BaLiF3—have been grown for solid state UV laser applications. Growth results and optical characterizations are discussed.
