Wave length difference between the absorption coefficients – cutting non-ferrous metals focusing into a spot smaller diameter – minimal heat affected zone, cutting thin and deformable metals
Excellent Beam Parameter Product • creation of the light is 200% more efficient • no expensive optical path • flexible optical fiber up to 300 m long • the focusing lens is sealed in the cutting head
Coefficient of efficiency Wall-plug efficiencies greater than 30% considerably lower running costs
Maintenance costs 50% longer servicing intervals 50% lower servicing costs No moving parts or mirrors - reducing maintenance requirements and operating costs
Laser diodes substitution • fiber laser is modular, built from multiple laser units • allows the laser system to incorporate reserve modules and power margins • could be supplied in bigger case for further gradual upgrade
