20/400 NuMATCH LMA Double Clad Fibers - 1

Typical Applications High power fiber lasers Military, industrial and medical Precision Matched Passive LMA Double Clad Fibers Nufern's Large Mode Area (LMA) and Polarization Maintaining LMA (PLMA) passive double clad fiber are ideal for high power fiber lasers and amplifiers used in military, industrial, and medical applications. These fibers feature a 20 micron diameter core and 400 micron diameter clad size with a low NA (0.065) core. They are precision matched to their active Yb-doped 20/400 LMA and PLMA matched counterparts to ensure excellent splice compatability and low loss. As with all Nufern standard Large Mode Area (LMA) fibers, these fibers are proof-tested to 100 kpsi, an industry requirement for long term reliability. They utilize the latest fiber design and NuCOAT™ coating technology to ensure excellent preservation of beam quality and extended operating life at the high power levels demanded by today's industrial fiber laser applications. These precision matched fibers are available in both non-PM and PANDA-style PM fibers. Features & Benefits NuCOAT™ fluoroacrylate coating — Greater fiber durability in extreme environmental operating & storage conditions LMA core design — Useful for transmitting high CW powers "Few" moded core design — Easy to maintain single mode LP01 beam through fiber & components PANDA-style stress structure for increased birefringence — Superior optical performance and uniformity All fiber proof tested to > 100 kpsi — Critical for ensuring long term reliability when coiling Operating Wavelength (nominal) 1060 nm 1060 nm Core Attenuation < 50.0 dB/km @ 1300 nm < 30.0 dB/km @ 1300 nm Cladding Attenuation < 15.0 dB/km @ 1095 nm < 15.0 dB/km @ 1095 nm Geometrical & Mechanical Prooftest Level > 100 kpsi (0.7 GN/m2) > 100 kpsi (0.7 GN/m2) These precision matched fibers are included in our precision matched sets - see PLMA-YDF-20/400-M and LMA-YDF-20/400-M 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.
