Smart Product Number: PM-EYDF-17/200
17/200 Erbium/Ytterbium Co-Doped Double-Clad Fiber
Nufern’s proprietary rare earth doping technology is used to deliver Er:Yb co-doped fibers with industry leading power conversion efficiency. Nufern's PM-EYDF-17/200 offers two important attributes much needed for continuous wave and pulsed fiber lasers and amplifiers at 1550 nm. The PM PANDA-style configuration enables the design of lasers and amplifiers with linearly polarized output. In addition, the large core/clad ratio (17/200), enables the design of short length pulsed amplifiers capable of delivering much higher pulse energies and peak powers than conventional single-mode Er/Yb fibers.
