Applications

Cutting thin foil copper

Cutting

• High quality cutting of thin foils • Good beam quality (M2<1.6 ) provides small spots and high irradiances

• Superb edge quality achieved though longer pulses (up to 2000 ns)

• Ideal for metal foils used in battery production

• Copper and aluminium foil (typically <30 μm in thickness)

• Coated metal foil (typically 60 – 120 μm in total thickness)



Applications

Cutting

Cutting Copper






• Faster cutting of sheet metal • Up to 3 mm in thickness for some metals

• Higher average power (up to 200W) increases productivity

• Higher pulse energy (1.5 mJ) provides up to 40% increase in cutting speed

• Compared to legacy G4 at this beam quality (1mJ max.)



Applications
