A fiber laser (or fibre laser in Commonwealth English) 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, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing.
The machines for laser engraving and laser marking are the same, so the two terms are sometimes confused by those without relevant expertise. The impact of laser marking has been more pronounced for specially designed "laserable" materials and also for some paints. These include laser-sensitive polymers and novel metal alloys. [2]
Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the laser beam to the material. A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material.
Material processing: cutting, welding, marking; nonlinear fiber optics: broadband fiber-nonlinearity based sources, pump for fiber Raman lasers; distributed Raman amplification pump for telecommunications. Holmium YAG (Ho:YAG) laser 2.1 μm Flashlamp, laser diode Tissue ablation, kidney stone removal, dentistry. Chromium ZnSe (Cr:ZnSe) laser
Lasers are used in optical disc drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic and free-space optical communications, semiconductor chip manufacturing (photolithography, etching), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and ...
IPG pursued raising the maximum wattage of fiber laser technology. [23] Between 2002 and 2003, IPG developed multi-kW industrial class fiber lasers. This was accomplished by combining the output beams of several 100-W fiber lasers. [22] In 2006 IPG raised more than $90 million, net of proceeds, in an initial public offering. [24]
