LIEKKI™ Er80-4/125 and Er80-8/125 fibers are very highly doped large mode area erbium fibers suitable for medium-power amplifiers and lasers. Good spliceability, high doping and a large core make these fibers ideal for medium peak power pulse amplification in the eye-safe 1.5 μm wavelength region. High erbium concentration reduces required application fiber length considerably while providing strong gain and reduced non-linear effects.
LIEKKI™ Er80-8/125 fibers can be used also with 980 nm pumps.
