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

(2+1) x1 multi-mode pump & polarization-maintaining signal combiner is specially designed to be used in the field of high-power polarization-maintaining fiber lasers and polarization-maintaining fiber amplifiers. 2-channel multi-mode pump energy and 1-channel signal energy are combined into A single double-clad optical fiber enables pump energy and signal energy to be transmitted in the same optical fiber. The pump absorption efficiency is high, the insertion loss is low, the power of a single arm can withstand up to 300W, and the performance is stable and reliable.
