Nufern launches two new fibers into its family of high power ytterbium-doped triple clad products.

EAST GRANBY, CT – January 23, 2006 — Nufern, the largest independent manufacturer of fiber intensive sub-assemblies and specialty optical fibers, announced today the expansion of their ytterbium-doped triple clad fiber product line.

Nufern’s new PM-YTF- 5/105/125 and PLMA-YTF-30/300/330 offer geometries and properties that compliment the previously released PLMA-YTF-20/300/330 and LMA-YTF-22/400/480 triple clad fibers.  Designed with the PANDA stress structure, these polarization maintaining ytterbium-doped fibers introduce an additional layer of glass around the second or “pump cladding” to contain pump light.

Using this “glass-on-glass” construction enables higher temperature operation and allows for easier splicing to fiber pigtailed pumps.  Triple clad all glass fibers also offer mechanical advantages when free space coupling of signal and pumps is required.  The hard outer cladding allows for the use of standard ferrule assemblies which enables precise alignment of the injected seed signal. 

“These new additions to our family of triple clad fibers offer our customers a wider range of fiber geometries from which to choose,” said Bryce Samson, Vice President of Business Development.  “The combination of the triple clad structure and large mode area technology allow our customers enhanced reliability and performance in the design of high power fiber lasers and amplifiers.”
