A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. They are related to doped fiber amplifiers, which provide light amplification without lasing. Fiber nonlinearities, such as stimulated Raman scattering or four-wave mixing can also provide gain and thus serve as gain media for a fiber laser.

 

The maximum size of sheet metal that Laser Cutting Machine HECF3015IE-500 can cut is 3000mm×1500mm. The products will have smooth edge with high quality surface finish, small kerf width and little heat effect. Therefore, the machine is especially suitable for cutting sheet metal.
