摘要：

We report blue-light generation using a first-order quasi-phase-matched second-harmonic generation (QPMSHG) in LiTaO3 waveguide. A first-order periodically domain-inverted structure can be fabricated using a quick heat-treatment technique. We have examined the dependence of the depth of the fabricated domain-inverted region on its width, which critically affects the conversion efficiency of SHG, and designed an optimum domain-inverted structure for the QPMSHG device. As a result, 15 mW of blue light was generated for a conversion efficiency of 10.3%.
