报道了两层堆积的六方周期极化LiNbO3S(PPMgOLN)中二次谐波(SHG)产生的深蓝非线性切伦科夫辐射。基于两个靶PPMgOLN绕与平面成30°角垂直旋转的轴线的直接键合，在每个二次谐波C erenkov环上显示出12个亮点，是单个PPMgOLN的两倍。实验结果与理论结果相吻合，为三维PPMgOLN的制备提供了良好的应用前景。
We report the dark blue nonlinear Cerenkov radiation by the second harmonic generation (SHG) in a two-layer-stacked hexagonal periodically-poled-MgO: LiNbO3s (PPMgOLNs). Based on the direct wafer bonding of two target PPMgOLNs rotating around the axis perpendicular to the plane with an angle of 30o, twelve bright spots as twice of those in a single PPMgOLN are shown at each second-harmonic C erenkov ring. The experimental results agree with the theoretical ones and present a promising application in the fabrication of three-dimensional (3D) PPMgOLNs.
