…utilization and rapid throughput necessary for
economically viable LTPS.
The excimer laser beam profile is also homogenized to
construct a highly uniform (so-called "top hat") profile along
its entire length and width. This is required to produce a consistent melt that, in turn,…

…grating length (see Fig. 3).
The Coherent Excistar laser outputs a
3 × 6 mm beam that has a uniform (top
hat) intensity distribution in the long direction and a Gaussian profile in the shorter dimension. Optics reshape the beam in
the NORIA system such that it can write
FBGs…
