Abstract
A calculation technique based on the Dipole Electron Shifting model is applied to investigate the nonlinear optical properties of the crystals of langasite family. The d 11 component of nonlinear optical susceptibility tensors is determined for La 3 Ga 5 SiO 14 , Ca 3 Ga 2 Ge 4 O 14 , La 3 Ga 5 . 5 Ta 0 . 5 O 14 La 3 Ga 5 . 5 Nb 0 . 5 O 14 crystals. The results of the calculations are compared with the experimental ones, described in literature.
采用基于偶极电子位移模型的计算方法研究了langasite族晶体的非线性光学性质。测定了la3ga5 sio14、ca3ga2 ge4o14、la3ga5的非线性光导率张量的d11分量。5塔0。5 O 14 La 3 Ga 5。5nb 0。5 O - 14晶体。计算结果与文献中描述的实验结果进行了比较。
