The (6+1)×1 Multimode Pump & Signal Combiner is a high-power optical component engineered for advanced fiber laser and fiber amplifier systems. Designed to efficiently combine six multimode pump inputs with one signal input into a single double-clad output fiber, this combiner delivers outstanding pump coupling efficiency and stable signal transmission. The signal propagates through the fiber core while all pump light propagates through the inner cladding, enabling high-brightness and high-power operation in a compact and reliable structure.
