abstract
The results of theoretical and experimental studies of the influence of crystalline structure on the nonlinear optical response of both metals and semiconductors are presented. It is shown that lattice disordering leads to the decrease of both anisotropy and the absolute value of the quadruple second order nonlinear susceptibility in aluminum and third order nonlinear susceptibility in silicon. These results are in agreement with experimental data.
