An X-cut and a Z-cut Li-deficient, non-congruent LiNbO 3 crystal were prepared by carrying out Li-poor vapor transport equilibration (VTE) treatment on one mm thick congruent plates at 1100 ยฐC for 170 h. From the measured optical absorption edges (OAE), the Li 2 O content is evaluated to be 47.74 ยฑ
