Ytterbium-Doped Double-Clad Fiber

YDC-1100-8/230 for fiber lasers

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

Applications:

CW fiber lasers from 1060 to 1110 nm (up to 500 W)
CW amplifiers

A double-clad, high-efficiency Yb-doped fiber, the YDC-1100-8/230 is appropriate for use in moderate power fiber lasers, such as those typically used in laser marking applications. StockerYale's low-index high-adhesion polymer serves as the outer cladding of the YDC-1100-8/230, 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.
