| Abstract: | A theoretical method on constituent chemical bonds of complex crystals based on the dielectric theory of solids has been proposed systematically, the independent nonlinear optical tensor co-efficients dij of some typical NLO cxystals with complex structures have been quantitatively calculated. Theoretical values agree with experimental data satisfactorily.This work shows that our method has a good application in dealing with optical nonlinearities of complex crystals, it also would be useful in designing or modifying new NLO crystal materials. |
