(N+1)×1 High Power Reverse Pump Combiner

High power reverse pump combiners (also called counter pump combiners) are specifically designed for especially high power fiber lasers. These combiners are usually mated with the forward optical path to form a bi-directional pump structure to obtain higher amplification efficiency and higher output power.
