A variety of materials, including most metals such as stainless steel, copper, brass, titanium, and many more, can be laser-milled. Femtosecond lasers are an essential tool for drilling, surface structuring (i.e., hydrophobic/hydrophilic), 3D milling/shaping (molds for micro-optics or stamps), engraving, polishing, or cutting metals.

They are also an important tool for indirect metal processing as traditional milling tools, made from hardened steel, PCD, WC, are often produced using femtosecond lasers.

Milling complex 3D structures into various metals with high accuracy and efficiency is no longer a challenge by equipping CARBIDE and PHAROS lasers with BiBurst.
