…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,…

Diffractive beam homogenizers typically generate a line by transforming the laser spot into a repeating series of small, closely spaced dots. Depending on the specific technology used, this type of line suffers from various deficiencies. With high coherence lasers for example, this approach can…

…11 Each oscillator beam enters the beam forming module 1 at a pulse energy of 1 Joule and is spatially formed by a telescope to fit the area of a subsequent homogenizing stage. After beam homogenization the beams are extended and overlayed within module 2. Since overlaying the beams and adding their…
