(N+1)×1 High Power Pump and Signal Combiners

(N+1)×1 Multimode Pump and Signal Combiners can be used for high power fiber lasers and fiber amplifiers. These devices can be used to combine several pump lasers and couple that power with a seed signal. Manufactured using our proprietary methods, the product series includes (6+1)×1, (18+1)×1, (36+1)×1 and other reasonable configurations are available.
