Легированное тулием-иттербием с двойной оболочкой TYDF-DC-7/125

Tm-Yb-Codoped Double Clad fiber

 

Application notes:

TYDF-DC-7/125 series is specially designed for highly efficient pumping with MM pump sources at 915/975nm. Pumping with conventional sources near 790 nm is also possible, as well as core pumping with EDFL operating at 1550-1600nm.
