Abstract

6.5 mol.% MgO-doped LiNbO₃ (MgLN) single crystal has been grown by the Czochralski technique. The MgO-doped crystal shows a shift in the absorption edge towards shorter wavelengths and a three orders of magnitude increase in the photorefractive damage resistance compared to the congruent LiNbO₃ crystal (CLN). This material has been periodically poled (PP) at room temperature by applying electric field, and the coercive field is 5 KV/mm, which is about 1/4 of that for congruent LiNbO₃. Periodic poling of 1 mm thick 6.5 mol.% MgO-doped LiNbO₃ substrates has been successfully performed and its operation in a femtosecond second-harmonic generation at room temperature. The performance of quasi-phase-matched second harmonic generation with a 1mm thick PP MgO:LN was compared with that of the second harmonic generation with the PP CLN at room temperature. The PP MgO:LN exhibited better performance.
