TM

Yb600-20/125

Large Mode Area Ytterbium Doped Fiber

LIEKKI
TM Yb600-20/125 fibers are amplifier fibers with large core to cladding area ratio. The fibers have high photodarkening resistivity and a short application length. LIEKKI
TM Yb600-20/125 fibers are currently only available as double cladding (Yb600-20/125DC) fibers.

Applications Features Typical device specification

High peak power, moderate average power amplifiers High photodarkening resistivity Large core to cladding area ratio, short application length Marking Matching 6+1:1 pump to signal combiner is available LIEKKI
