Pockels effect (plural Pockels effects)
An effect that changes or produces birefringence in an optical medium induced by electric field.
If this susceptibility itself depends upon the electric field, one can obtain a nonlinear optical effect of magneto-optical parametric generation (somewhat analogous to a Pockels effect whose strength is controlled by the applied magnetic field). Source: Internet
Only certain crystalline solids show the Pockels effect, as it requires lack of inversion symmetry ** Kerr effect (or quadratic electro-optic effect, QEO effect): change in the refractive index proportional to the square of the electric field. Source: Internet
The index of refraction is changed by the Pockels effect, thus changing the direction of propagation of the beam inside the prism. Source: Internet
