RE-doped DCFs are the best fibers for fabrication of high-power fiber lasers and fiber amplifiers, because they can be excited by the high power multi-mode LD. Since ZBLAN fibers have unique emission bands like 1.3 μm-, 1.46 μm- and 2.8 μm-band, developments of new equipments utilizing these emission bands are possible. Especially, 2.9 μm band fiber lasers using Er-doped DCF is studied actively around the world.The octagonal shape DCFF developed by our original fiber manufacturing technology is easy to handle and offers excellent excitation efficiency.
双包层掺杂稀土光纤因为在高功率多模激光二极管中可以被激发而用于制高功率光纤激光器和光纤放大器,它的唯一特片是在1.3 μm-, 1.46 μm- and 2.8 μm带宽发射光谱.世界上2.9um波段的光纤激光器都用Er-doped DCF 光纤,Fiberlabs研发的8边形的双包层光纤可以提供更好激发效率和方便控制激发.
