EAST GRANBY, CT–February 4, 2013– 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 rare earth doped 2mm active fibers by introducing the all-glass double clad Holmium doped fiber and expanding its Thulium doped fiber products with two new offerings.
The first fiber of a new Ho-doped all-glass double clad series continues the history of collaborative research and development between Nufern and a small group of its customers at the forefront of mid-IR fiber lasers research. The Ho-doped fiber features a unique all-glass cladding design with a 40µm diameter Ho-doped core, a glass inner cladding diameter of 250µm, a 320mm 0.22NA index depressed outer glass cladding for the pump radiation and a fluoroacrylate outer polymer jacket (40/250/320/400) . This new Ho-doped fiber is optimized for resonant pumping at 2050nm using Tm-fiber lasers and achieves higher output power than similarly operated polymer-based double-clad Ho-doped fibers because of the all-glass pump waveguide design. The optimal operating wavelength range for these fibers is around 2150nm, making them an ideal choice for a variety of medical lasers as well as power scaling for a host of military laser applications.
The two new Tm-doped fibers include a highly doped Tm-fiber for core pumping, enabling very short laser cavities required in producing ultra-fast fiber lasers and a lower concentration 25/250 Tm-doped double-clad fiber that operates in the shorter wavelength region of the gain spectrum with improved performance.
Dr. Adrian Carter, CTO and Asia/Pacific Sales Director, states, “Nufern continues to work with its customers in the area of 2mm fiber lasers and to build upon our fiber expertise and manufacturing capabilities to help achieve better performance from both Ho and Tm-doped devices. We anticipate that these 2mm fibers will see growth in the areas of ultra-fast lasers as well as medical, military and industrial applications over the next several years.”
