Most laser line generator manufacturers
specify line uniformity as the variation in
the intensity profile from the average intensity value over a given region. Usually, this…

lasers are typically limited to cutting glass
in straight lines because their round output
beam must be reshaped into a long, thin
line in order to distribute the intense heat
generated at the surface. In contrast, the…

line on the work surface, rather than a circle (which is the way
laser beams are most commonly focused).
This is necessary in order to adequately distribute the intense heat generated by the laser.
However, this geometry means that the glass
is always being heated along a line
