…ways. For example, both optomechanical
mounts and optics themselves may respond to temperature changes in a way that alters beam pointing or the
beam shape. This changes the geometry or position of
the focus, which becomes more critical when producing
smaller features. Again,…

…ranges, high-power laser diodes can produce beam profiles
that are far from Gaussian in shape, resulting in a beam that may
exhibit an "M"-shaped longitudinal profile with a large gap. In such
cases, it is difficult to extend the beam into a very uniform line. At
Coherent, we…

…homogeneous line beam length
in the range of 250-750 mm to match the substrate size to
be processed in the experiments. The line beam width is
0.25-0.4 mm, depending on the line length. Such a high
aspect ratio of the line beam field is generated by independently shaping the two…

…variations in laser output, as well as changes in optical alignment within a beam delivery system, and degradation in the performance of individual beam delivery optics (such as a drop in reflectivity on a mirror). Pulse shape is also an important parameter, particularly for applications in the…

…technologies, pulsed excimer lasers offer
the highest pulse energy (up to 2 J). Plus,
the large rectangular beam produced by
excimer lasers can easily be shaped and
homogenized to match the geometry of
typical CFRP surface preparation applications. Together, these…

…tasks. The output beam from
these lasers can readily be shaped into a
line ranging from 3 to 24 mm in length,
with a width of 3 to 12 mm, enabling tremendous flexibility in cladding implementation. Since the area to be clad is typically
larger than the beam, it is moved across…

…in certain
smartphones. Here, again, the excimer output is formed into the shape
of a long, thin line beam, which we
call "UV blade." The finished panel is
scanned underneath the line beam in
order to ablate an ultra-thin layer of
material holding it to the rigid…

…the
ablated metal. Plus, the excimer-based process is fast. For example, when using a high
power excimer laser (e.g. 300W), the beam
can be shaped to cover about 1-2cm2.
The previously described SÜSS MicroTec
ELP300 with integrated high power excimer laser is capable of seed…

The merits of an all flat-top beam
profile
The high UV pulse energy of the excimer laser reaching up to one Joule in the

energy stabilized operation mode, supports shaping large beams with a flat-top
energy density distribution as demanded
