Lightel’s Pump Combiners Serve Fiber Lasers and Fiber Amplifiers

July 23, 2019 Alix Paultre

Lightel’s high-power pump combiners are mainly used to combine the power of several multimode lasers, and are available for applications with up to 36 laser sources and total powers of up to 8,000 W. Offering a rate of efficiency up to 90 percent and higher, the combiners are available with different fibers and fiber combinations, with polarization-maintaining (PM) configurations also possible.

This technology is used for both fiber lasers and erbium-doped fiber amplifiers (EDFAs). In addition to stability and reliability, high power transfer efficiency is crucial. Therefore, it is particularly important to adhere to the strict requirements that apply to production. Custom designs for single-mode and polarization-maintaining (PM) fibers are also available upon request. The fibers can also be provided with fiber Bragg gratings.
