1.5um (2+1)x1 Pump & Signal Combiner Fiber Combiner
(2+1) x1 multi-mode pump & signal combiner is specially designed to be used in the field of high-power fiber lasers and fiber amplifiers. It combines 2 multi-mode pump lights and 1 signal light into a single double-clad fiber. , the signal light travels through the core of the fiber, and the pump light travels through the cladding, realizing the transmission of pump light and signal light in the same optical fiber. It has high pumping efficiency, low insertion loss, can withstand power up to 300W per arm, and has stable and reliable performance.
