Fiber lasers will cut more efficiently (particularly on thin metal), consume less power, be easier to maintain, and cut reflective metals more efficiently than CO2 lasers.

The fiber lasers are appropriate to shear the non-ferrous metals like stainless steel, steel, brass, copper, and aluminium. Even though the fiber lasers are applied on the metals in gigantic quantities, the fiber lasers are not generally appropriate to shear the non-metal materials.

Fibre laser sources have extremely long working life with a typical working life of approximately 100,000 hours before even they start to fail, many times that of a CO2 laser.
