Active Fibers

Doped active fibers for highly reliable fiber laser systems and amplifiers

Our active fibers are offered in a variety of dopants such as ytterbium, erbium or erbium-ytterbium co-doped. They are specifically designed to meet the performance you need for fiber lasers used in a variety of applications, including optical amplifiers (EDFA) and LIDAR.
