The photorefractive effect can be understood considering the following mechanisms:
photoexcitation and trapping of charge carriers, transport of the photoexcited carriers …

The term “photorefractive effect” literally refers to a change in the refractive index of a
material caused by light. Recently, however, the term has been used for the subset of such …

The role of defects in the photorefractive effect is known in principle: their photoionization in
the brighter regions of a photorefractive crystal, illuminated by an inhomogeneous light …

This is the first volume of a set of three within the Springer Series in Optical Sciences, and is
devoted to photorefractive effects, photorefractive materials, and their applications. Since the …

This chapter provides a detailed review of theoretical work on the photorefractive effect. The
physical model of photorefractivity used here, which now seems well established by many …

The photorefractive effect first observed in LiNbO3, LiTaO3, BaTiO3, and KTN [1, 2] showed
that these materials underwent a change in index of refraction after illumination with low …

This is the first of two volumes that review, for the first time, all major aspects of
photorefractive effects and their applications. Photorefractive effects in electro-optic crystals …

Tailoring of photorefractive crystals and optimization for certain applications requires
detailed knowledge on microscopic origins of the photorefractive effect. Illumination …

Photorefractive materials have been assuming ever increasing prominence in the non-linear
optics field due to their unique capability for displaying strong non-linear effects at milliwatt …

Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …
