Gaussian beam matlab. Apr 30, 2020 · Download and share free MATLAB code, including functions, models, apps, support packages and toolboxes The Script is used to model the behaviour of a Gaussian beam propagating in the Z direction with spherical wavefronts in the paraxial region. The simulation follows a numerical approach to model the wave's behavior as it propagates in free space, interacts with a concave mirror, and continues propagating after reflection. In optics, a Gaussian beam is an idealized beam of electromagnetic radiation whose amplitude envelope in the transverse plane is given by a Gaussian function; this also implies a Gaussian intensity (irradiance) profile. This MATLAB script simulates and visualizes the intensity distribution of a Gaussian beam as it propagates through space. My code is below, as well as the function I found to do the propagation. The beam is specified by its wavelength (visible part of the electromagnetic spectrum), power and the value of its waist. The simulation is based on scalar diffraction theory and includes the effects of beam divergence, wavefront curvature, and the Gouy phase shift. Sep 6, 2023 · I am attempting to simulate the propagation of gaussian Bessel beam (as produced by an axicon) using Fourier propagation (Fresnel propagation?) but I am having some problems. And chances are very very small that anyone is going to volunteer to research the topic and write the code for you just because you posted that you "want" the code. This project simulates the propagation of a Gaussian beam using Fourier optics in MATLAB.
