{wiki=Photon-induced_electric_field_poling}
Photon-induced electric field poling is a technique used to manipulate the optical and electronic properties of materials, particularly nonlinear optical crystals. This method utilizes the interaction of light (photons) with a material to induce a change in its polarization state, thereby creating an electric field across the material. This induced electric field can align the dipoles of the material in a particular direction, achieving a state known as poling.
