6 July 2005. Nufern in East Granby, Conn., is offering the next optical fiber in its ytterbium-doped triple-clad fiber family. The ytterbium-doped fiber consists of a 22-micron core diameter; 400-micron inner glass cladding diameter with numeric aperture of 0.22; and an outer glass cladding of 480-micron with a high-numerical-aperture 0.46 polymer cladding. "The successful introduction of our polarization maintaining PLMA-YTF-20/300/330 triple-clad fiber at Photonics West this year encouraged us to expand the product line to include a fiber with larger cladding diameter for higher power operation", says Kanishka Tankala, vice president of operations at Nufern. "The introduction of the new 22/400/480 fiber ensures that our fibers and fiber laser modules are compatible with one of the most universal, industry standard power delivery fibers -- 400/480, thus easing connectorization and diode pump power delivery issues for our customers."
