…of beam width is the width at which the beam intensity has fallen to 1/e² (13.5%) of its peak value. This is derived from the propagation of a Gaussian beam and is appropriate for lasers operating in the fundamental TEMoo mode or closely. In reality, many lasers exhibit a significant amount of beam

…laser beam is coincident with a TEM00 (Gaussian profile) beam of a different wavelength. The donut beam depletes the population of excited fluorophores via stimulated emission. This beam shape serves to constrict the volume of fluorophores that the TEM00 beam excites. The donut-shaped depletion beam

…understandable why two beams of identical power and diameter leave different burn marks on a substrate if one beam features a Gaussian or near-Gaussian profile (maximum intensity in the beam center), while the other beam features a so-called donut profile (very little power in the beam center).…
