    Growth and Optical Homogeneity of Hf:Mn:Fe:LiNbO3 Crystals with Various [Li]/[Nb] Ratios by DAI Li, HE Keqi, HAN Xianbo, WANG Yuning

    Published 2020-06-01
    “…The Hf:Mn:Fe:LiNbO3 crystals were grown with various [Li]/[Nb] ratios (0946, 105, 120 and 138) by the Czochralski method In order to explain the influence of different [Li]/[Nb] ratios for the defect structure of Hf:Mn:Fe:LiNbO3 crystals, the segregation coefficients of the Hf4+, Fe3+ and Mn2+ ions in the crystals were carried out with an inductively coupled plasmaatomic emission spectrometer, and we analyze the optical homogeneity of Hf:Mn:Fe:LiNbO3 crystals by the birefringence gradient method The result show that the segregation coefficients of the Hf4+ ions increase to 10 nearly when [Li]/[Nb] ratios is 138, and the [Li]/[Nb] ratios of increase in the crystal with the [Li]/[Nb] ratios increase in the melt Hf:Mn:Fe:LiNbO3 crystals have better optical homogeneity when [Li]/[Nb] ratios achieve 138 This experimental result is explained by the occupancy mechanism of LiNbO3 crystals and lithium vacancy defect…”
