Advantages of Femto LASER machining

• Heat affected zone avoided due to cold ablation

• No deposits, no recasts

• Machining of a wide range of materials

• Cutting function (ablation) available

• Depending on application: no needs of amount process

No damage caused

to adjacent structure

No heat transfer to

surrounding material

Nomicrocracks \ Hot dense

ion/electron
