我们已经测量了在空气中在2.33 eV的基本光子能量下来自TiO 2（金红石）的（110）面的SH强度的方位角依赖性。SH强度的图案示出对于p -入/ p -出偏振配置的双重对称性、对于p -入/ s -出偏振配置的四重对称性以及对于s -入/ p -出偏振配置的双重对称性。从实验和理论分析的结果，我们得出结论，所观察到的SH光是由表面电偶极极化产生的。
We have measured the azimuthal angle dependence of the SH intensity from the (110) face of TiO2 (rutile) in air at the fundamental photon energy of 2.33 eV. The pattern of the SH intensity shows two-fold symmetry for the p -in/ p -out polarization configuration, four-fold symmetry for the p -in/ s -out polarization configuration, and two-fold symmetry for the s -in/ p -out polarization configuration. From the results of the experimental and theoretical analyses we have concluded that the observed SH light is generated from the surface electric dipole polarization.
