Coherent proprietary rare earth doping technology is used to deliver Er:Yb co-doped fibers with industry-leading performance and reliability. These fibers demonstrate high pump conversion efficiency and high power operation without rollover due to 1 µm ASE, enabled by the double clad fiber design. The large core of the fiber allows for shorter fiber lengths in high power amplifiers to reduce the impact of non-linear effects.
