…(FIGURE 1).
Of currently available ultraviolet laser
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…

…energy source may be a lamp or, more commonly, another laser. Electrical pumping can be via a DC current (as in laser diodes), an electrical discharge (noble gas lasers and excimer lasers) or a radio-frequency discharge (some CO2 lasers). In a conventional (incoherent) light source like a lightbulb,…

…(FIGURE 1).
In this technique, a pulsed excimer laser line beam is
scanned over the a-Si film. Silicon efficiently absorbs the
308nm excimer output. This high absorption, combined with
the high pulse energy of the excimer laser, makes it possible
to achieve near-complete…
