1.5um (2+1)x1 Pump & Polarization-maintaining Signal Combiner PM Fiber Combiner

The (2+1)×1 multi-mode pump & polarization-maintaining signal beam combiner is specially designed to be used in the field of polarization-maintaining high-power fiber lasers and fiber amplifiers. It combines 2 multi-mode pump lights and 1 polarization-maintaining signal light. Entering a single double-clad optical fiber, the signal light travels through the core and the pump light travels through the cladding, achieving transmission of pump light and signal light in the same optical fiber. It has high pump efficiency and extinction ratio, low insertion loss, can withstand power up to 300W per arm, and has stable and reliable performance.
