The Script is used to model the behaviour of a Gaussian beam propagating in the Z direction with spherical wavefronts in the paraxial region. org/wiki/Gaussian_beam). 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. 0. BeamLab is an award-winning set of simulation tools for beam propagation through optical devices and waveguides in your familiar MATLAB ® environment. Diaz Matlab visualizations of analytical descriptions of Hermite-Gaussian and Laguerre-Gaussian Vortex Beams BeamLab is a comprehensive set of simulation tools for beam propagation through optical devices and waveguides in the MATLAB environment. The code defines a function bessel_gaussian_beam that takes the order of the Bessel function, beam waist, wavelength, grid size, and the number of grid points as inputs and outputs the intensity profile of the beam. With a steadily growing library of easy-to-use functions, it is highly flexible in waveguide and input field design.
