Ytterbium doped fiber YDF-DC-10/125

Photodarkening free Yb-doped DC fiber

APPLICATION NOTES:

Ytterbium doped fiber YDF-DC-10/125 series is designed for operation without any power degradation in a high-peak-power cladding pumped amplifiers. The highest clad absorption over the market allows usage of only 3 m of such fiber (with 976 nm pump) for efficient amplification.
