Refractive index (RI) is a complex number comprising a real refractive index and an imaginary part: the absorption (or extinction) coefficient. The analysis of refractive index by the Surfoptic Imaging Reflectometer yields an approximation to the real part of the refractive index. The well established technique of ellipsometry, by contrast, can determine both the real refractive index and the e...

We study the anisotropic nature of the Kerr nonlinear response in a beta-barium borate (β -BaB2O4, BBO) nonlinear crystal. The focus is on determining the relevant χ(3) cubic tensor components that affect interaction of type I cascaded second-harmonic generation. Various experiments in the literature are analyzed and we correct the data from some of the experiments for contributions from cascad...

The paper addresses optical solitons in magneto-optic waveguides that are studied using Kudryashov’s law of nonlinear refractive index the presence chromatic dispersion and Hamiltonian-type perturbation terms. trial solution approach yielded a variety soliton solutions, which listed this paper.

The current paper studies highly dispersive optical solitons with the aid of Kudryashov’s integration algorithm. governing model employs sextic power law nonlinear refractive index. inter-modal dispersion term is absent from model. scheme retrieves dark and singular to

Laser diffraction is one of the most widely used methods for particle size analysis of micron and submicron size powders and dispersions. It is quick and easy and provides very consistent, repeatable information. Since these instruments use scattered light intensity to determine particle size, knowledge of the optical properties, specifically the complex refractive index of the material being a...
