How Fiber Laser Cutting Machine Work?
Fiber laser machine 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. 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.
Widely applications of fiber laser cutting machine,do you know how fiber laser cutting machine work ?
Efficiency is good, but the energy not producing coherent laser light must be dissipated with a cooling system, placing a practical limit on the amount of power a commercial cutting of welding device can use. Fiber lasers use optical fibers, “pumped” with diodes to create solid state laser cutting machines with far fewer components and no gas consumables, lowering operating costs. They also convert pumped energy into laser light at up to twice the efficiency of gas lasers and typically use half the power. The wavelength of light emitted by fiber lasers is also shorter than CO2, typically 1 um, with a very small focal diameter, offering high intensity heating that can be an order of magnitude higher than CO2 technology at similar power levels. They can also cut highly reflective materials such as brass or aluminum, which could damage the optics in a CO2 machine.
