By using the Z-scan method we studied the third-order nonlinear optical parameters of
several aminobenziliden-1, 3-indandione (ABI) derivatives that have previously been shown …

In this work we present numerical results of the far field intensity distributions obtained for a
Gaussian beam after crossing a thin nonlinear nonlocal material that exhibit nonlinear …

Light scattering, whether caused by desired or spurious elements, is considered one of the
main phenomena that present great challenges for the nonlinear (NL) optical …

Doping of materials by suitable additives can dramatically modify the physical characteristics
of the complex systems. In this paper, we investigate the role of gadolinium concentration on …

This paper considers the calculation of the nonlinear losses induced in a circular aperture
enlighten by a focused Gaussian beam (GB) subject to optical Kerr effect. Such a problem …

Analytical solutions are derived using a straightforward mathematical treatment that
accurately describes the power of a TEM_00 Gaussian beam transmitted through or around …

We report on the characterization of silica aerogel thermal optical nonlinearity, obtained by z-
scan technique. The results show that typical silica aerogels have nonlinear optical …

Goodness of fit is demonstrated for theoretical calculation of z-scan data based on beams
propagating in the nonlinear medium and the Fresnel–Kirchhoff diffraction integral in …

The motion of two interactional solitons is investigated in nonlinear media with an
exponential nonlocal response. A differential equation describing the motion trajectories of …
