A fiber laser source is a laser type that utilizes optical fibers as its gain medium, employing rare-earth-doped fibers like erbium, ytterbium, or thulium. These materials amplify light when pumped by high-powered laser diodes, exciting the rare-earth ions to emit light. 

Fiber laser sources are known for their efficiency, reliability, and compactness, offering numerous advantages over other laser types. Notably, they can generate high power output with excellent beam quality, making them suitable for various applications. Their efficiency enhances productivity in production systems, although they can be costly. Fiber lasers are widely used in applications such as cutting, welding, marking, engraving, and drilling of various materials, including metals, plastics, and ceramics.

The list below showcases the leading brands of fiber laser sources globally. Each brand is accompanied by a general overview, advantages. You can select from these brands according to your budget or specific application needs.
