Fiber lasers are a type of laser that use optical fibers as the gain medium to produce laser light. These fibers are typically doped with rare-earth elements like ytterbium or neodymium, which help amplify the light when energized. Fiber lasers are known for their efficiency, compact size, and ability to produce high-quality beams. One of the key advantages of fiber lasers is their versatility in various applications, including cutting, welding, and marking materials. They can operate at different wavelengths, making them suitable for processing metals, plastics, and other materials. Their robust design also allows for reliable performance in industrial settings.
