CUDE – Direct diode laser system for cutting of mild and stainless steel



The challenge is to develop a 9xx nm diode laser system that robustly delivers 1 kW at 7.5mm*mrad. The diode laser system will provide optical and electrical interfacing for industrial application in the area of cutting and the system will demonstrate diode laser cutting of mild steel up to 6 mm, stainless steel up to 4 mm, and aluminium up to 3 mm.


Plate cutting is the largest application field in a five billion Euro worldwide market for laser macro machining. Potential applications are laser cutting of different materials and thicknesses like:

  • Mild steel up to 6 mm
  • Stainless steel up to 4 mm
  • Aluminium up to 3 mm

CUDE aims to establish an important milestone by validating the cost/performance relationship of novel direct diode lasers in an industrial environment. From the supplier side, there is benefit in standardisation and interfacing of technical equipment. This gives the supplier the opportunity to fit in different applications and to break into different markets. The user benefits from the low cost of ownership and simple implementation through standardisation and interfacing. Both DPI and Prima expect to benefit from the predicted growth in this segment of cutting.
