What is a Fiber Laser?
A fiber laser is a type of laser that utilizes an optical fiber doped with rare-earth elements such as ytterbium, neodymium, or erbium to generate laser light. The optical fiber acts as both the gain medium and the laser cavity, resulting in a highly efficient and compact laser source. Fiber lasers are distinguished by their ability to deliver high power with excellent beam quality, making them suitable for a wide range of industrial applications.
The core of the fiber laser is the optical fiber, which is carefully engineered to facilitate the amplification of light. As electrical current passes through the fiber, it excites the dopant atoms, causing them to emit photons that are amplified and guided along the fiber to produce a high-intensity laser beam. This process allows fiber lasers to achieve exceptional performance and reliability.
