ABSTRACT

Yb and Zn co-doped LiNbO3 single crystal rods which had a diameter of 2 mm and a length of 15~25 mm were grown by micro-pulling down (μ-PD) method. The single crystals were successfully grown and had a uniform diameter and a smooth surface without crack. We realized of LiNbO3 single crystals were hexagonal structure to compare with peaks of LiNbO3 powder by Raman spectra. The threshold level of Zn concentration which is effective for optical damage were observed as about 1 mol% with IR transmission spectra.
