We show that incoherently coupled soliton pairs are possible in biased photorefractive
crystals, under steady‐state conditions. These solitons can propagate in bright‐bright, dark …

We study one-dimensional steady-state photorefractive screening solitons in a bulk
strontium barium niobate crystal. We compare measurements and calculations of the soliton …

BaTiO3 and BaTiO3: Ce thin films with good surface morphology and tetragonal perovskite
structure were fabricated on quartz substrates by pulsed-laser deposition technique at a …

In this paper the response purely refractive of a thin nonlinear material, in the z-scan
technique experiment, is modeled as a lens with a focal length that is a function of some …

A search for contributions to the reaction ep→ eπ 0N∗ from photon–odderon fusion in the
photoproduction regime at HERA is reported, at an average photon–proton centre-of-mass …

(Na1− xKx) 0.5 Bi0. 5TiO3 (NKBT)(x= 0.1, 0.2, and 0.3) thin films with good surface
morphology and rhombohedral perovskite structure were fabricated on quartz substrates by …

It is shown that the propagation of steady-state spatial solitons in a bismuth titanium oxide
(Bi_12TiO_20) photorefractive crystal is strongly affected by the presence of concomitant …

We present an experimental study of the photorefractive self-defocusing in LiNbO3: Fe, Mg
crystals which is investigated by using the Z-scan technique. The self-defocusing effect …

The shape of two-dimensional solitary beams propagating in photorefractive media with an
externally applied field is studied. The analytical results indicate that, for both focusing and …

As a result of the original theoretical analysis in different approximations we show that the
steady-state photoinduced photorefractive lens formed under an external transverse dc …
