NuUF Ultrafast Fibers

Ultrafast fibers - cost effective power scaling and superb beam quality

Double clad, Yb doped, active fiber, chirped pulse, power scaling, PLMA, PM, femtosecond, high beam quality, low photodarkening, frequency doubling

NuUF fibers offer customers an opportunity to scale up power while avoiding the costs and risks associated with solid state designs. Our fibers provide a path to a seamless transition to a higher powered system with significantly reduced $/W.

Our PM, large mode area (PLMA) Ytterbium doped active fibers (YDF) and passive matched Germanium doped Fibers (GDF) are tailored to meet key requirements for ultrafast laser designs. These specialty fibers feature polarization maintenance, dispersion control, high beam quality, low photodarkening, and highest absorption.

These fibers are also highly suitable for other applications that are sensitive to nonlinear effects including narrow linewidth amplification, second harmonic generation, frequency doubling, and short pulse amplification.
