What is a Fiber Laser and How Does It Work?
A fiber laser is a kind of laser where the active gain medium is a optical fiber doped with rare earth elements like erbium, ytterbium, or neodymium. In this case the generation and amplification of the laser light happens in the fiber and the light is efficiently guided and enhanced within the fiber.
To generate laser light fiber lasers utilize the energy from a pump laser diode which is injected into the doped fiber. This energy will result in the excitation of the dopant atoms and cause them to emit photons. The amplified photon is produced by a stimulated emission process and this is how the highly focused and precise laser beam is created. Owing to their efficient designs, the more advanced fiber lasers offer high power output, excellent beam quality and low maintenance cost making them useful in many different scientific and industrial applications.
