Fiber lasers can cut copper, brass and aluminum much better and more safely than CO2 because the beam is more readily absorbed and not reflected. Fiber laser operating costs are typically half of what a CO2 system can offer due to the lower electrical consumption and high electrical efficiency of Fiber lasers.
How does a fiber laser cutting machine work?
Fiber lasers use optical fibers, “pumped” with diodes to create solid state laser cutting machines with far fewer components and no gas consumables, lowering operating costs. They also convert pumped energy into laser light at up to twice the efficiency of gas lasers and typically use half the power.
