(2+1)x1 Multimode Pump & Signal Combiner

The (2+1)x1 Multimode Pump & Signal Combiner is a high-performance passive optical component specifically designed for high-power fiber laser and fiber amplifier systems. It efficiently combines two multimode pump inputs with one signal input into a single double-clad output fiber, where the signal propagates through the core and the pump light propagates through the inner cladding. This configuration enables simultaneous transmission of pump and signal light within the same fiber, ensuring high pump efficiency, low insertion loss, and high output stability.

Engineered for demanding power-handling environments, the combiner supports up to 300 W power per branch, offering exceptional reliability for industrial and scientific laser applications. With its wide wavelength compatibility, robust thermal performance, and excellent mechanical stability, this combiner is ideally suited for integration into next-generation fiber laser architectures.
