…redistributed from the beam center to the edges in the far field (which is usually begins at 100 mm from the last lens surface). This can be seen clearly in the ray trace diagram (see Figure 4.) Because a Powell lens is a type of cylindrical lens, it only homogenizes the beam in one dimension. So,…

…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 CFRP surface preparation applications. Together, these characteristics enable rapid…
