(1+1)×1 or (2+1)×1 High Power Pump and Signal Combiners

Lightel’s (1+1)x1 and (2+1)x1 Multimode Pump and Signal Combiners can be used for high power fiber lasers and fiber amplifiers. These devices can be used with a pump laser(s) to couple that power with a seed signal. Manufactured using our proprietary methods, these combiners provide superior performance and are available with a wide variety of fiber types.
