A diffractive beam splitter is a precision optical element designed based on micro/nano optical structures, and is essentially a specially designed diffraction grating. By precisely etching microstructures on the surface of a substrate material and utilizing the principle of light diffraction, it can precisely split a single incident laser beam into multiple output beams with uniform energy or distributed according to a specific ratio, forming a one-dimensional or two-dimensional spot array. Compared with conventional beam splitters, diffractive beam splitters can achieve more complex energy distribution and higher beam parallel processing capability, providing greater flexibility and efficiency for modern laser applications. A one-dimensional diffractive beam splitting grating can split a single incident laser beam in a single direction into a row (1×N) of discrete beams with uniform energy. A two-dimensional diffractive beam splitting grating can split a single incident laser beam on a plane into a two-dimensional array (M×N), forming multiple parallel beams with highly uniform energy.
