Abstract

Mg:Er:LiNbO 3 crystals were grown by the Czochralski method. Their UV-Vis absorption edges and OH - transmission spectra were measured in terms of the defect structure. The absorption edges shift towards a shorter wavelength with increasing Mg concentration. The dependence of the shift mechanism of the absorption edge on the defect structure was discussed in detail. The OH - absorption bands shift from 3486 cm-1 to 3535 cm-1 when the Mg concentration exceeds a threshold value. It is considered that the 3535 cm-1 absorption band corresponds to the (MgNb) 3-– OH - complexes.
