Photorefractive effect - Wikipedia
网页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.

网页The electro-optic effect translates the internal electric fields induced by the inhomogeneous space-charges into a modulation of the material refractive index. This is the main mechanism for photorefraction in inorganic and organic crystals [1].
Photorefractive Material - an overview | ScienceDirect Topics
网页Photorefractive materials are doped light-sensitive electro-optic materials in which optical radiation creates mobile charge carriers which redistribute themselves to create an induced space-charge field. This electrostatic field in turn modulates the refractive index which phase modulates the optical beam.
