Profile analysis of a Gaussian laser beam

, 2018
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

Beamdiameter — Development of software for a laser beam profiler

SoftwareX
A laser beam profiler (LBP) is essential for characterizing laser beams by providing detailed intensity distribution measurements using internationally standardized algorithms. Typically expensive, LBPs are often inaccessible to low-budget research labs.
