Profile analysis of a Gaussian laser beam

It was carried out the study and analysis of the profile image of a Gaussian laser beam, in two different color scales, RGB and gray, using the MATLAB computational tools, from which some beam properties were determined, as well as their distribution of intensities, width in the FWHM, 1/e and 1/e2 , his waist, and the percentages of concentrated energy for each of the regions with intensity values greater than or equal to the FWHM points, 1/e and 1/e2 , both one-dimensionally and two-dimensionally.
