| Abstract: | In this paper, a series of Hf,Ce co-doped lithium niobate crystals with various HfO2 concentrations were grown by Czochralski method. The ultraviolet-visible absorption spectra and the infrared transmittance spectra were measured to study defect structure of the crystals. The optical damage resistance was measured by the transmitted facula distortion method. The results showed that the optical damage resistance of Hf:Ce:LiNbO3 was greatly improved when the Hf-doping concentration was above 4 mol%. |
