Since its inception, the fiber laser has attracted users because of its large gain and the ability to produce continuous lasing. The quasi-continuous wave for industrial applications further broadens fiber lasers’ appeal.IPG Photonics CorporationThe modern fiber laser is pumped by high-power, multimode single-emitter diodes or diode bars, typically through a cladding surrounding a single-mode core. This single-mode core is typically 5 to 12 µm in diameter. The double-clad fiber consists of an inner single-mode core doped with the appropriate rare-earth ions such as neodymium, erbium, ytterbium and thulium. The cladding is made of undoped glass that has a lower index of refraction. The pump light is injected into the cladding and propagates along the structure, passing through the active core and producing a population...Read full articleRelated content from Photonics MediaARTICLESA History of the Laser: 1960 - 2019In 2020, the laser will celebrate its 60th anniversary.
