Fiber vs Co2 Laser Cutters

The laser-cutting industry has transitioned in recent years from using carbon dioxide (CO2) lasers to fibre laser-cutting systems.

The light source of a fibre laser-cutting system, commonly known as fibre lasers in the industry, is created by diodes. This light is channelled and amplified through a fibre-optic cable and is straightened and focused by a lens onto the material to be cut. The laser requires no optical mirrors, while the focusing lens is sealed in the cutting head.


  • The speed is several times higher than that of a CO2 laser.
  • Fibre lasers use less electricity than CO2 lasers
  • Efficiency of a fibre laser is increased by more than 30%, whilst the degree of efficiency for a CO2 laser is only 14%.
  • Fibre lasers can also cut copper, brass and aluminium better and more safely than CO2 lasers, as the beam is readily absorbed and not reflected.
  • Additional advantages of fibre laser cutters include the absence of beam path bellows that are necessary in CO2 systems, low operating costs, owing to wear-free semiconductor excitation, lower electricity consumption and substantially less maintenance.
