WebJan 1, 2024 · The application of alternative beam shapes is a current research topic to stabilize, accelerate and extend laser-based powder bed fusion of metals, e.g. by tailoring the microstructure. Static beam shapes and sizes limit the theoretically possible process and geometry freedom. WebThe wavefront of the laser optics is planar at the beam waist and approaches that shape again as the distance from the beam waist region increases. Many laser optics systems …
