Spectroscopic characterizations and optical damage resistance of Zn:Yb:Er:LiNbO3 crystals

Zn:Yb:Er:LiNbO3 crystals have been grown. The infrared transmission spectra were measured and discussed in terms of the spectroscopic characterizations and the defect structure of the Zn:Yb:Er:LiNbO3 crystals. The optical damage resistance was characterized by the transmitted beam pattern distortion method. The optical damage resistance of Zn (6.0 mol%):Yb:Er:LiNbO3 crystal is about two orders of magnitude higher than that of other crystal. The dependence of the optical damage resistance on the defect structure was studied.
