Paper Abstract

This paper focuses on femtosecond laser cutting and drilling using a patented technology for suppressing the conicity generated by the ablation saturation. We will show that it is now possible to use a high power femtosecond laser, of several hundreds of watts, for zero taper cutting by considering a precession movement on the beam like a donut beam shaping and by applying a beam splitting on this engineered beam to feed several standard scanners.
