How Fiber Laser Machines Work
Fiber laser marking machines work by transmitting a high-frequency laser beam through optical fibers. The laser beam, through a set of high-end optical equipment, is directed to the surface of the material that is to be marked. The marking is done through surface modification via annealing, ablation, or engraving. The laser beam can be adjusted in speed and depth depending on the type of material. This laser marking process is non-contact and very rapid, thus causing very small amounts of thermal injury to the material being marked.
