Tīmeklis2016. gada 1. apr. · The results reveal that there exists an optimal sphere size for the maximum scattered field which is determined by the topological charge, beam waist radius, and beam center position. Since the development of the generalized Lorenz-Mie theory, electromagnetic scattering by arbitrary beams has drawn growing interest. … Tīmeklis2016. gada 28. jūn. · We introduce a family of asymmetric Laguerre-Gaussian (aLG) laser beams. The beams have been derived via a complex-valued shift of conventional LG beams in the Cartesian plane. While propagating in a uniform medium, the first bright ring of the aLG beam becomes less asymmetric and the energy is …

In optics, a Gaussian beam is a beam of electromagnetic radiation with high monochromaticity whose amplitude envelope in the transverse plane is given by a Gaussian function; this also implies a Gaussian intensity (irradiance) profile. This fundamental (or TEM00) transverse Gaussian mode describes … Skatīt vairāk The Gaussian beam is a transverse electromagnetic (TEM) mode. The mathematical expression for the electric field amplitude is a solution to the paraxial Helmholtz equation. Assuming polarization in the x direction … Skatīt vairāk Power through an aperture With a beam centered on an aperture, the power P passing through a circle of radius r in the … Skatīt vairāk When a gaussian beam propagates through a thin lens, the outgoing beam is also a (different) gaussian beam, provided that the beam travels along the cylindrical symmetry axis of the lens. The focal length of the lens $${\displaystyle f}$$, the beam waist radius Skatīt vairāk Hermite-Gaussian modes It is possible to decompose a coherent paraxial beam using the orthogonal set of so-called … Skatīt vairāk The geometric dependence of the fields of a Gaussian beam are governed by the light's wavelength λ (in the dielectric medium, if not … Skatīt vairāk The spot size and curvature of a Gaussian beam as a function of z along the beam can also be encoded in the complex beam parameter q(z) given by: Introducing this complication leads to a simplification of the Gaussian beam field equation as … Skatīt vairāk As a special case of electromagnetic radiation, Gaussian beams (and the higher-order Gaussian modes detailed below) are solutions to the wave equation for an electromagnetic field in free space or in a homogeneous dielectric medium, obtained by … Skatīt vairāk http://www.optique-ingenieur.org/en/courses/OPI_ang_M01_C03/co/Contenu_14.html Tīmeklis2024. gada 26. apr. · Laguerre–Gaussian mode sorter based on multi-plane light conversion.
