Pump/Combiner
A fiber optic active pump combiner (also called a doped fiber pump combiner) is manufactured by coupling the pump
power directly into a doped fiber (e.g. erbum-ytterbium). In a traditional pump combiner application, the end-user
splices the combiner’s passive fiber output to a doped fiber, possibly resulting in back scattering. Lightel’s active pump
combiner eliminates the splice to the gain element and any backward signal to the pump lasers is reduced.
