EAST GRANBY, CT –January 24, 2012– Nufern, a leading U.S. manufacturer of specialty optical fibers, fiber lasers and amplifiers and fiber optic gyro coils, announced today it is expanding its line of fibers by introducing two Holmium doped double-clad fibers, thereby increasing the operational wavelength range of active fiber offerings to 2150 nm.
The two Ho-doped fibers are the result of years of research and development between Nufern and a small group of its customers interested in mid-IR fiber lasers. Both Ho-doped fibers feature a double-clad design and the recently developed NuCOATTM coating technology, which affords greater durability and longer life. The Ho-doped standard fibers are offered in two geometrical configurations – a 25 µm core diameter with a 250 µm clad diameter; and a 40 µm core diameter with a 400 µm clad diameter. These fibers achieve 60% efficiency when resonantly pumped with a Tm fiber laser. The optimal operating wavelength range for Ho-doped fiber is between 2000 and 2150 nm, making them an ideal choice for a variety of medical lasers as well as power scaling for a host of military laser applications.
Dr. Adrian Carter, CTO and Asia/Pacific Sales Director, states, “Nufern continues to look for ways to add more value to our customers in a wide range of applications. We realized through our relationships with our customers that there was a need for fiber products that extend the operating wavelength range beyond 2000 nm. We therefore worked with our customers and built upon our fiber expertise and manufacturing capabilities to develop Ho-doped fibers. We anticipate that these fibers will see considerable growth in medical, military and industrial applications over the next several years.”
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.
