Application of fiber laser

Fiber laser has a wide range of applications, including laser fiber communication, laser space long-distance communication, industrial production, shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, printing roller, metal and non-metal drilling / cutting / welding (brazing, water quenching, cladding and deep welding), military defense science and technology security, medical instruments and equipment Large scale infrastructure construction, as the pump source of other lasers, etc.

Fiber laser refers to the laser using rare earth doped glass fiber as gain medium. Fiber laser can be developed and designed on the basis of fiber amplifier. Under the action of pump light, it is easy to increase the formation success rate density in the optical fiber, resulting in the "particle number inversion" of the laser energy level of the laser working material. When a positive feedback loop (forming a resonant cavity) is properly added, the laser oscillation output can be formed.
