用光学二次谐波干涉显微镜观察了化学计量比LiNbO_3(PPSLN)和LiTaO_3(PPSLT)中的周期性极化磁畴结构。利用D31SHG张量分量,可在PPSLN中获得三维断层图像。在PPSLT中,使用D22分量获取顶面和底面的图像。讨论了有无干涉时倍频图像的差异。
Periodically poled domain structures in stoichiometric LiNbO3 (PPSLN) and LiTaO3 (PPSLT) are observed using an optical second harmonic generation (SHG) interference microscope. Three-dimensional section images can be obtained in PPSLN using d31 SHG tensor component. In PPSLT, the images of top and bottom surfaces are obtained using d22 component. The difference in SHG images with and without interference is discussed.
