Profile: Nufern is a manufacturer of application-specific specialty optical fiber and integrated fiber laser & amplifier modules. We expertize in fiber and fiber integration. Nufern designs and manufactures optical fibers from photosensitive to rad-hard to high-power double clad fibers. Nufern's NuPOWER™ of active fibers are used for high-powered lasers and amplifiers. We offer active fibers available in single clad, double clad, and triple clad variants. These fibers have brightness, narrow linewidth and extreme power stability to satisfy the most demanding applications. Our erbium active fiber is perfect for single and multi-channel C- and L-band amplifiers and ASE sources and small form factor devices. Our thulium active fiber is used as eye-safe fibers for use around the 2 µm wavelength. Our monolithic fiber laser modules incorporate the NuPOWER family of industry-leading double-clad fibers. Our nufern series of ytterbium fiber laser modules are designed as reliable robust sources that integrated into OEM applications for industrial and manufacturing environments. Its application covers the fields such as marking and engraving, micromachining, micro-adjustment, high resolution soldering and graphic art imaging. Our nufern amplifiers are available with a various options including pre-packaged, pre-spliced diodes, end cap assemblies, pump dumps, connectors, OEM packaging and optimized configurations for non-standard wavelengths. Its application covers the fields such as sensing, range finding, LIDAR, marking, micromachining and precision material processing. Our NuFIRE laser system is a complete, self-contained fiber laser designed to achieve high performance specifications for reliability and precision. Our NuAMP SF series amplifiers include input isolation & input/output interlocks to prevent system failure. We are an ISO 9001:2000 certified company.
