It is well known that the optical response of a medium depends on the local field acting on
an individual emitter rather than on the macroscopic average field in the medium. The local …

Robust propagation of self-trapped light over distances exceeding 25 diffraction lengths has
been demonstrated for the first time in plasmonic nanosuspensions. This phenomenon …

In this work, nonlinear refraction properties of 3nm sized silver sulfide (Ag2S) semiconductor
nanocrystals dispersed in the dimethyl sulfoxide with varying concentrations are reported …

The thermo-optical properties of colloidal silver nanoparticles (AgNPs) are investigated
under a low power laser irradiation at 532nm. Colloidal AgNPs are synthesized by …

In this study, we experimentally investigated the nonlinear optical properties of Au
nanoparticles (Au NPs) that were prepared in pure distilled water using the laser ablation …

New colloidal solutions of gold nanoparticles (AuNP), using castor oil as a nontoxic organic
dispersant agent, were prepared via three different methods. In all three cases …

We study nonlinear propagation of light in colloidal suspension of metallic nanoparticles, in
the regime of particles surface plasmon resonance. We show that the propagation exhibits …

We investigate the nonlinear propagation of light beams with complex phase and intensity
structures, including a Gaussian-embedded vortex, a Bessel vortex, and a Bessel-cosine …

The nonlinear optical responses of gold nanoparticles dispersed in castor oil produced by
sputtering deposition were investigated, using the thermally managed Z-scan technique …

We have investigated the nonlinear response of the silver nanoparticle samples in a low-
power regime of electromagnetic field based on nonlocal thermo-optic models. In this work …
