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 $\rm La_3Ga_5SiO_{14}$, $\rm Ca_3Ga_2Ge_4O_{14}$, $\rm La_3Ga_{5.5}Ta_{0.5}O_{14}$ $\rm La_3Ga_{5.5}Nb_{0.5}O_{14}$ crystals. The results of the calculations are compared with the experimental ones, described in literature.

Key words: nonlinear optics, polarizabilities, langasite
