Abstract

A series of Zn:In:Fe:LiNbO~3~ 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 In^3+^ doping concentration in melt, the segregation coefficients of both Zn and In ions decrease. The optical damage resistance of Zn:In:Fe:LiNbO~3~ crystals was studied by the transmitted beam pattern distortion method. It is found that the optical damage resistance of Zn:In(3mol%):Fe LiNbO~3~ crystals is two orders of magnitude higher than that of Zn:Fe:LiNbO~3~. (Β© 2009 WILEY‐VCH Verlag GmbH & Co.
