A fiber laser is a type of laser that uses optical fibers doped with rare-earth elements, such as ytterbium or neodymium, to generate laser light. This technology allows for high efficiency and excellent beam quality, making fiber lasers suitable for various applications, including cutting, welding, and marking materials like metal and plastic. Fiber lasers are known for their compact size and low maintenance requirements compared to traditional lasers. They can produce high power outputs while consuming less energy, making them an environmentally friendly option. Their versatility and precision have made them increasingly popular in industries such as manufacturing and telecommunications.
