Pump and signal combiner for bi-directional pumping of all-fiber lasers and amplifiers(1)

Abstract We developed an all-fiber component with a signal feedthrough capable of combining up to 6 fiber-coupled multi-mode pump sources to a maximum pump power of 400 W at efficiencies in the range of 89 to 95%, providing the possibility … Continue reading
