Double-Clad Fiber Nufern's Neodymium doped PM-double clad fiber is specifically designed for efficient single mode operation around 1060 nm when cladding pumped at 808nm. A 6 urn mode field diameter allows low splice losses to standard single mode fibers and the 125 urn cladding diameter is compatible with a variety of industry standard pump combiners. The polarization maintaining design enables construction of pulsed and CW PM fiber amplifiers. Typical Applications Features & Benefits CW and pulsed fiber lasers Single-mode core — Perfect beam quality, compatible with standard single-mode fibers PM fiber amplifiers PANDA-style stress structure for increased birefringence — Superior optical performance and uniformity An alternative to Yb-doped fibers for Operating Wavelength (nominal) 1060 nm Mode Field Diameter 6.0 ± 1.0 urn @ 1060 nm Geometrical & Mechanical Second Cladding Material Low Index Polymer Prooftest Level > 100 kpsi (0.7 GN/m2) 7 Airport Park Road, East Granby, CT 06026 • 860.408.5000 • Toll-free 866.466.0214 • Fax 860.844.0210 E-mail info @ nufern.com • www.nufern.com Nufern products are manufactured under an ISO 9001:2008 certified quality management system.
