Efficient Ablation, further GHz Burst Polishing, and Surface Texturing by Ultrafast Laser

Ultrafast Lasers In article number 2302262, Mindaugas Gedvilas, Andrius Žemaitis, and Paulius Gecˇys present a novel precision fabrication method for the creation of 3D cavities in metal. Fresnel lens molds designed for LED diffusers are created utilizing the state-of-the-art layer-by-layer laser milling technique and femtosecond burst irradiation. The findings open new opportunities for industrial applications of ultrafast lasers.
