PM 5/125 Neodymium-Doped
nnnnDouble-Clad Fiber
nnnnNufern's Neodymium doped PM-double clad fiber is specifically designed for efficient single mode operation around 1060
nnnnnm when cladding pumped at 808nm. A 6 urn mode field diameter allows low splice losses to standard single mode fibers
nnnnand the 125 urn cladding diameter is compatible with a variety of industry standard pump combiners. The polarization
nnnnmaintaining design enables construction of pulsed and CW PM fiber amplifiers.
nnnnTypical Applications Features & Benefits
nnnnCW and pulsed fiber lasers Single-mode core — Perfect beam quality, compatible with standard single-mode fibers
nnnnPM fiber amplifiers PANDA-style stress structure for increased birefringence — Superior optical performance and uniformity
nnnnAn alternative to Yb-doped fibers for
nnnn1060 nm operation
