…INTENSITY
Conventional laser line patterns are often generated by cylindrical optics that produce a Gaussian line profile with
a bright center and fading ends. Coherent patented beam shaping optics spread the light into an evenly illuminated
line. The result is an exceptional, uniform…

…least one beam axis has a Gaussian
cross-section with only 25 % lift-off
effectivity. The entirely flat-top beam
characteristics of excimer laser lift-off
systems (Fig. 3), also along the short axis
of line beam systems, provide an 80 %
effective beam area and support…

…focused laser spot on the workpiece so that it departs significantly from the traditional, single-peaked Gaussian distribution. This research has shown that a beam consisting of a central Gaussian distribution spot, surrounded by another concentric ring of laser light, can often provide an effective…

…the intensity distribution on the plane perpendicular to the beam direction. The ideal laser beam has a radially
symmetric cross section: The intensity is greatest in the center and tails off at the edges, following a Gaussian profile. This is called the TEM00

…another. The best beam profile for drilling, etching and
ablation is generally Gaussian, with an intense center
point. Welding and 3-D manufacturing work best with a
flat-top profile, with intensity that rises quickly to a fixed
level and is then flat across the beam.
