Fiber laser VS Fiber coupled laser module

Fiber laser VS Fiber coupled laser module

Nov 17, 2020

Fiber laser refers to a laser that uses rare-earth-doped glass fiber as the gain medium. Fiber laser can be developed on the basis of fiber amplifier: high power density is easily formed in the fiber under the action of pump light, resulting in laser The laser energy level of the working substance is "particle number inversion", and when a positive feedback loop (forming a resonant cavity) is properly added, the laser oscillation output can be formed. At present, the power of fiber lasers can reach hundreds of watts.


Fiber lasers have a wide range of applications, including laser fiber communications, laser space telecommunication, industrial shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, and so on.


Compared with high-power fiber lasers in the watt and hundreds of watts, the fiber coupled laser module provided by Elite are mainly used in medical testing equipment and industrial instruments. The power is basically 1~300mw, and the wavelength range is 405nm~980nm. It is mainly used as a laser light source and does not require very high power. Its characteristics are low power consumption, small size and high beam quality. Different LD drivers can be equipped according to the customer's special purpose. It can also increase PD feedback to improve the stability and reliability of the laser module.
