Research Abstract

A new LiNbO_3 bulk crystal (cs-MgO : LiNbO_3)has been developed by including MgO combined with vacancy and the crystal successfully has the congruent point coincident with the stoichiometric point. Activities of all crystal-constituent elements including Mg and vacancy are unity. The cs-MgO : LiNbO_3 has a much more homogeneous composition than the conventional LiNbO_3 crystals and its SHG conversion efficiency is comparable to the optimum value reported.
