Laserbeam divergenceand spot size

Dec 20, 2021 — The technical explanation for adjusting aperture settings is fairly simple: the wider the aperture, the narrower your depth of field becomes.

This calculator computes the radiance of a laser beam propagating in a multi-mode or double-clad optical fiber. It can also be used for free space beams by replacing core diameter with focal spot diameter. Radiance is kind of a measure of beam quality with power included. At best radiance can only be conserved, not improved in optical components such pump combiners. Radiance is defined as
