| Abstract: | A series of Zn:In:Fe:LiNbO3 crystals were prepared by Czochralski method. The crystal composition and defect structure were analyzed by ICP‐OE/MS, UV–vis and IR spectroscopy. The results show that with increasing In3+ doping concentration in melt, the segregation coefficients of both Zn and In ions decrease. The optical damage resistance of Zn:In:Fe:LiNbO3 crystals was studied by the transmitted beam pattern distortion method. It is found that the optical damage resistance of Zn:In(3mol%):Fe LiNbO3 crystals is two orders of magnitude higher than that of Zn:Fe:LiNbO3. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
