A laser beam propagating in a photorefractive crystal generates a refractive-index profile
that deflects the beam to one side. This nonlinear deflection can be balanced by total …

We report the first observation, to our knowledge, of amplified scattering (beam fanning) in a
photorefractive polymer. The manifestations of beam fanning and the implications for two …

Based on a multi-three-wave mixing model, we theoretically study the resistance against
light-induced scattering in LiNbO_3: M (M= Mg^ 2+, Zn^ 2+, In^ 3+, Sc^ 3+) crystals. We …

The geometry of a total-internal-reflection (TIR) phase-conjugate mirror is investigated in the
framework of a two-dimensional model, based on the solution of nonlinear material …

We investigate asymmetric stimulated photorefractive scattering (fanning) in the framework
of a two-dimensional model, based on the solution of nonlinear material equations and …

Based on a multiwave mixing model, we explain the symmetrical and broad light-induced
scattering effect in LiNbO_3: Fe crystal sheets. Analytical results are given in the undepleted …

In this article, we have studied experimentally the threshold effect of incident light intensity
for the photorefractive light-induced scattering and signal beam amplification in doped …

We express the exact probability density distribution function as the product of a gamma
distribution and a series of associated Laguerre polynomials, with the expansion coefficients …

Stationary and dynamic properties of photo-induced light scattering (PILS) have been
studied as a function of the photorefractive crystal thickness. A mono-exponential growth of …

The effect of non-linear light scattering has first been recognized in 1966 by Ashkin et al.,
who observed the temporal evolution of a wide-angle scattering distribution when a crystal …
