EAST GRANBY, CT - January 25, 2011 - Nufern, a leading U.S. manufacturer of specialty optical fibers, fiber lasers & amplifiers and fiber optic gyro coils announced today it is substantially augmenting its new series of -HE long wavelength laser & amplifier fibers.
Nufern is expanding with a new family of rare earth doped, high efficiency (-HE) fibers at both the 1.5 and 2µm "eyesafe" wavelengths. At the shorter wavelength, the introduction of the Er:Yb 12/130-HE fibers is specifically aimed at high power applications where the improved slope efficiency results in negligible 1µm ASE through optimized glass composition. At the longer eyesafe wavelengths, we introduce the new Tm-doped LMA fibers, 10P/130-HE and 25P/400-HE, which are optimized for high efficiency under 790nm pumping through a process of Tm-ion cross relaxation. These new fibers for the first time, combine high efficiency and a low NA core to deliver excellent beam quality. In general, as with most Nufern rare earth doped fibers, these fibers are available in PM and non-PM versions and with matching passive fibers.
"Every year at Photonics West we strive to update our extensive list of high power, rare earth doped double-clad fibers with the latest in glass technology" says Dr. Adrian Carter, CTO and Asia/Pacific Sales Director. "By expanding our list of Gen VIII Yb-doped fibers and introducing a high efficiency eyesafe fiber series, we are responding to customers' demands for the latest glass technology to be applied across as many standard fibers as possible, ensuring compatibility and ease of use across their entire array of double clad fibers at all the key wavelengths of 1 µm, 1.5 µm and 2 µm".
All of Nufern's fibers are manufactured to exceptionally tight mechanical and optical tolerances. The resulting uniformity and efficiency helps to ensure high yield when the fiber is used in device manufacturing. All Nufern fibers are produced under an ISO 9001:2008 certified quality management system.
