The photovoltaic current density in crystals without a center of symmetry depends bilinearly on the components of the light polarization vector via a third‐rank tensor. For LiNbO 3 :Fe and LiNbO 3 : Cu the tensor properties are confirmed and three of the four non‐vanishing components determined. The dependence on impurity concentration and on photon energy is also investigated.
