Ytterbium-Doped Double-Clad Fiber

YDC-1100-20/250 for fiber lasers

High slope efficiency
High-adhesion lowindex polymer outer cladding
Superior humidity performance

Applications:

CW and pulsed fiber lasers from 1060 to 1110 nm
CW amplifiers

Adouble-clad, high-efficiency Yb-doped fiber, the YDC-1100-20/250 is currently used in CW and pulsed fiber lasers. StockerYale’s low-index high-adhesion polymer serves as the outer cladding, providing an NA of 0.48 for the pump radiation. The helical pump modes are effectively scrambled by the presence of flat sections in the boundary between the silica inner cladding and the low-index polymer outer cladding.
