…on a substrate if one beam features a Gaussian profile (maximum
intensity in the beam center) while the other beam features a so-called donut profile (very little to no power in the
beam center). In fact, there are many material-processing related applications such as cutting, welding,…

…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). Theory can sometimes predict the behavior of a beam, but manufacturing tolerances in lenses and…

…STED works.
A donut-shaped laser beam is coincident
with a TEM
00
(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

…can be made to agree exactly with the variance-based width definition for two modes, which he picks to be the
first two (the fundamental and donut modes). As the order of the
mode or mixture of modes increases, a difference between the knife
edge and variance-based beam widths is…

…portion of the beam.
Closer examination of the false color beam intensity
map from the CCD camera indicates the slight
appearance of a donut mode. Figure 2 shows a 640
nm laser where again the 84/16 beam data met
specification. But this time, increasing the data set to
