Flexible Ytterbium doped Double Clad Fibers, 11/70um

The DC-70/11-PM-Yb is an all-solid step-index fiber. The 11 µm polarization-maintaining core is strictly single-mode and does not rely on coiling to obtain its excellent beam quality.

The multimode pump light is guided by our proven airclad technology, ensuring low loss, high damage threshold and a large numerical aperture (NA). The large NA relaxes tolerances on coupling optics and facilitates the use of lower brightness diodes.

The fiber can be used in stand-alone power amplifiers or as a pre-amplifier fiber for our larger fibers like the DC-200/40-PZ-Yb  or the DC-150/30-PM-Yb.

A pump absorption of 12 dB/m at 976 nm enables very short amplifiers capable of handling very high power levels.
