In recent years, spatial self‐phase modulation (SSPM) with two‐dimensional (2D) materials
has attracted the attention of many researchers as an emerging and ubiquitous nonlinear …

In this work, the study of the nonlinear optical properties of poly eosin-Y phthalate solution
using the diffraction ring patterns and the Z-scan methods are presented. The diffraction ring …

In this paper, the nonlinear propagation dynamics of circular–linear edge dislocation beams
(CLED beams) in nonlocal media are studied theoretically. The transport formulae of CLED …

We report on the experimental observation of the diffraction pattern formed in the far-field
region when a high-power continuous-wave laser convergent or divergent Gaussian beam …

Abstract Poly (azaneylylidene-acylene)" DAZA" polymer has been synthesized and
characterized using different spectroscopic techniques. Self-diffraction ring patterns at far …

We demonstrate dark-hollow beam (DHB) generation based on cross-phase modulation
(XPM) in the hot Rb cell. It is found that a Gaussian beam (probe beam) can be converted …

Understanding the nonlinear optical effect of novel materials plays a crucial role in the fields
of photonics and optoelectronics. Herein, we theoretically and experimentally investigate the …

Colloidal silver nanocubes in solution were analyzed by the Z-scan technique in the
resonant and non-resonant regimes. Three different systems with particle sizes of 56, 99 and …

Nonlinear optical properties of metallic and oxide metallic nanoparticles have been
extensively studied as saturable absorbers in fiber-optic lasers in the infrared region for the …

A model to characterize the response of a thin media that can exhibit more than one
nonlocal nonlinear response when it is illuminated with a Gaussian beam in a z-scan …
