ABSTRACT

Nd2O3 0.2~0.8 wt.% doped LiNbO3 single crystals were grown by the Czochralski method. The ZnO doping by2~8 mole% can improve the resistance of optical damage. In this study, Nd : LiNbO3 single crystals with the periodicaldomain structure were obtained by CZ method.Key words Nd : LiNbO3, Czochralski, Periodical domain, QPM, Congruent composition, Constitutional supercolingCzochralski .. .. ....
