Coherent fibers enable power scaling by eliminating SRS and TMI and options include large mode area, polarization maintaining, double clad and triple clad geometries, and Ytterbium, Erbium, EYDF, and Thulium doped fibers. Our fibers feature high mode quality, high absorption, high efficiency, long life, and lowest photodarkening for demanding applications. We also offer passive precision matched fibers for use in laser and amplifier components that maximize beam quality and minimize splice losses. Leaders in double clad fiber technology
