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

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 …

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 …

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

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

We describe an improved mathematical model for photorefractive materials exhibiting hole-
electron competition where the constants accounting for electrical coupling between holes …

Ferroelectric materials derive their name by analogy with ferromagnetic materials, of which
have found great utility as memory storage media and magnetic field sensors. Crystals such …

We report on non-steady-state photocurrent measurements of photorefractive sillenites
grown in an oxygen-free atmosphere. A sufficient increase in the photoconductivity of …
