摘要: 给出了各向异性磁光薄膜非线性第2谐波的极化矩阵,推演了该矩阵在不同对称表面上元的个数及其分布;导出了此磁光薄膜在自剩磁磁化强度分别平行于[001],[110]和[111]晶面且外施电场作用于相应表面时,相应表面上的非线性第2谐波极化强度,以及均匀反射空间相应表面激发的相应极化组合非线性第2谐波的强度;求出了该谐波光场的两个可能的取向角;分析讨论了相应表面上出现两个可能取向的原因及其影响因素.Abstract: Nonlinear second-harmonic polarization matrix from the anisotropy magnetic-optical thin film,numbers and distribution of elements of the matrix at different symmetrical surfaces have been provided.The nonlinear polarization of the corresponding surface and the nonlinear second harmonic field aroused by the corresponding surface of evenly reflection space for the magnetic-optical thin film is also presented,when the magnetization strength of magnetic self-surplus parallel to the [001],[110] and [111] crystal surface respectively and the outside electric field does action to responding surface.The orientation angle of two possibilities of this harmonic smooth site is given.The cause factor and the reason of two possible orientations to correspondingly surface are analysized and discussed.
