Beam Splitter DOE
The collimated laser light is incident onto an array (1 x N or M x N) of Beam Splitter DOE to split the input beam into N beams. The N output beams make some separation angle with the Beam Splitter DOE and there exists the desired zero-order beam for an odd number of beams (N). The focusing lenses are often used to achieve the output at the desired working distance.
Beam Shaper DOE
This set up comprises a laser source, Beam Shaper DOE, scan system/lens, and a working surface. The light passed through the Beam Shaper DOE distributes the Gaussian beam energy into a uniform intensity of either a circular or rectangular top-hat profile.
