摘要：

We reported the periodic poling (PP) MgO-doped (6.5 mol%) congruent LiNbO3 (MgO:LN) and its operation in a femtosecond second-harmonic generation at room temperature. Because the switching field of MgO:LN is similar to5 kV/mm, which is approximately one fourth that of the congruent LN field, PP of thicker MgO:LN wafer was performed by means of applying external field at room temperature. The performance of quasi-phase-matched second-harmonic generation (SHG) with a 1-mm thick PP MgO:LN was compared with that of the second-harmonic generation with the PP congruent LiNbO3 (CLN) at room temperature. The PP MgO:LN exhibited better performance. (C) 2004 Elsevier B.V. All rights reserved.
