DC-135/14-PM-YB
Single-mode Polarization-Maintaining Double-Clad Ytterbium Gain Fiber

-

Truly single-mode
Large 15 µm MFD
Solid step-index
Polarization-maintaining
High NA pump cladding
High pump absorption

Applications
- Pulsed fiber amplifiers (fs, ps, ns)

The DC-135/14-PM-Yb fiber is a truly single-mode, all-solid step-index gain
fiber. The 14µm polarization maintaining core delivers diffraction limited
output in a single-mode covering the entire Yb emission bandwidth; The
mode quality does not depend on coiling and is stable over time.
The multimode pump light is guided by our proven airclad technology, ensuring high reliability, high damage threshold and large numerical aperture
(NA); the large NA relaxes tolerances on coupling optics.
The fiber is available with sealed ends and is compatible with commercially
available pump/signal combiners.
