Abstract

Femtosecond lasers play a significant role in the industrial processing of metals, including cutting masks, drilling foils, texturing molds, and engraving. This research explores methods for maximizing the removal rate of metals. The highest removal rate and best quality can be achieved using pulses shorter than 300 fs and optimal laser fluence. We also demonstrate the potential of femtosecond laser polishing of laser-machined surface, resulting in surface roughness well below Sa<1 μm. Examples to be showcased include manufacturing gratings for FIR spectroscopy, drilling stainless steel, deep engraving, and polishing dies for coin minting.
