Beam shaping components are a type of diffractive optical element (DOE) that modulate the beam's wavefront through microstructures, converting a Gaussian-distributed incident laser beam into spots with uniform or arbitrary intensity distributions in shapes such as lines, rectangles, squares, or circular lines. Compared to other beam shaping methods like aspherical lens groups or birefringent lens groups, DOEs offer advantages such as small size, array shape, integrated, and high optical energy efficiency. They can create sharp, distinct boundaries between the processing and non-processing areas. These elements are applicable in fields such as laser welding, laser cutting, laser scribing, laser drilling, and medical treatments.
