Abstract

Laser beam shaping is increasingly used in laser material processing, additive manufacture, and biomedical fields. Output profiles can tailored to the requirements of the application, and do not need to be limited to typical Gaussian or super Gaussian appearances. Beam shaping can be achieved through refractive or diffractive optical elements (ROEs / DOEs), or more complex approaches such as coherent beam combination, and multiplane light conversion [3]. ROEs can provide beam shaping solutions with high transmission and shaping efficiency in a single optical element, without the need for bulky or complex systems.
