What is Fiber Laser Cutting Technology?
Fiber laser cutting technology is a method that utilizes a high-powered laser beam to cut through materials with extreme precision. The laser beam is generated by optical fibers doped with rare earth elements such as erbium, ytterbium, or neodymium. These fibers amplify the laser light, producing a highly focused and powerful beam. The laser beam is then directed through a cutting head that precisely controls the path of the cut. This technology is known for its efficiency, precision, and versatility, making it suitable for cutting various materials including metals, plastics, and composites.
