…coupled into the interaction zone using a Coherent beam focusing module that incorporates a novel aspheric optic to create an extended "top hat" beam intensity profile in the axis lateral to the core stream (figure 4). The result is that the detection efficiency is now relatively insensitive to the…

…process 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, yields the…

…effective 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 from 1 to 10…
