How to use diffractive beam splitters?
A diffractive beam splitter is a diffractive optical element used to split a single collimated laser beam into several beams with optical characteristics like original beam. Usually beams are separated into 1D or 2D arrays and may be arranged regularly or irregularly. The diffractive beamsplitter allows to create any type of spot arrays (1D, 2D or irregular) while maintaining high efficiency and uniform distribution of energy in the spots.
