Fiber Lasers Fiber Lasers A fiber laser is a laser in which the active gain medium is an optical fiber, doped with rare-earth elements. In layman's terms, it is a type of solid state laser, where the laser light passes through the fiber, amplifying it to create a high quality beam, which enables marking. The key features of the fiber lasers include: Ÿ Marks a wide range of materials including most metals and plastics Ÿ No consumables are required Ÿ Minimal maintenance is required Smallest footprint in any laser technology Ÿ Air cooled Ÿ Can be mounted in any orientation Ÿ Running on 1060 - 1080nm, this reliable technology is designed to withstand the vigors of a production environment, and is best suited to continuous production environments.
