BALTIMORE, Maryland - June 3, 2003 - Nufern Introduces PM Double-Clad Fiber - Flexible Design for Multiple Applications Requiring Low Cost Devices. Nufern, the largest independent manufacturer of application-specific optical fiber, introduces a general purpose Ytterbium-doped (Yb) polarization maintaining (PM) double-clad fiber for applications requiring low-cost fiber laser and amplifier sources, such as laser marking, pumps for fiber amplifiers, and IR sources for frequency doubling. This double-clad fiber features an industry standard 125 mm format and Panda-style stress elements. The fiber is designed for ease of handling, including splicing and cleaving, and has photosensitive properties similar to SMF28TM that allow Bragg gratings to be written directly into an active fiber.

“ The general purpose nature of this double-clad fiber makes it an ideal choice for applications where cost and compatibility are an issue,” says Nufern Vice President of Sales, Vinnie Rodino. “The fiber’s telecom-type geometries are compatible with the low-cost pump diodes and fiber-based components now available on the market. And as a double-clad product, the fiber offers an alternative to our large-mode-area (LMA) series of fibers, which are designed for high power applications. By designing a lower cost, double-clad fiber, with similar handling properties to standard transmission fiber, we can provide customers with a cost effective means to double-clad technology.”

Nufern’s PM-YDF-5/125 fiber has a core diameter of 5.5 µm, clad diameter of 125 µm, birefringence of 3.0 x10-4, and a cladding NA of 0.46. The fiber is also available in a non-PM version.
