The values of electronic polarizabilities of La3+, Ga3+, Si4+, O2- ions are specified using new experimental data about optical activity of La3Ga5SiO14 crystals. A calculation technique based on the dipole electron shifting model is applied to estimate linear electrooptic coefficients for the La3Ga5SiO14. Wavelength dependences of the both linear electro-optic tensor components r11 and r41 are calculated.
