The photorefractive effect is a nonlinear optical effect seen in certain crystals and other materials that respond to light by altering their refractive index.[1] The effect can be used to store temporary, erasable holograms and is useful for holographic data storage.[2][3] It can also be used to create a phase-conjugate mirror or an optical spatial soliton.
