Nufern provides the US defense industry with force multiplying optical fiber-based technologies from sensors to HEL. Founded in 2000 we are a US company experienced at servicing the US government, its agencies, foreign governments under license as well as myriad allied military and aerospace contractors from our volume manufacturing plant in Connecticut. Nufern is equally capable and experienced at executing rated (DX, DO) and commercial term transactions satisfying customer needs and FAR. Our products are working on Mars, the depths of our oceans and many places in between.
Nufern is a registered defense contractor with the US state department. Our state of the art, ITAR compliant headquarters and flex manufacturing facilities in E. Granby, CT have hosted the development of many sensitive products & technologies. We strive to make our customers successful on every project we do.

CW Kilowatt-Class Amplifiers
Near diffraction limited beam quality at highest power
Nufern has leveraged its preeminent specialty fiber business to create a family of compact, high performance, kilowatt-class amplifiers with diffraction limited beam quality designed specifically for defense applications.
These compact & rugged systems provide requisite high beam quality, high efficiency, and narrow linewidth making them optimal for spectral or coherent beam combination applications.
Fast MRO support is available from our depot service integrated with our high production capacity facility and direct and open access to our engaged scientists & technical development team. Field service and application assistance is provided from that same motivated team of experts.
CW Kilowatt-Class Amplifier Accessories
Most clients building proof of concept and prototype demonstration systems choose to utilize our broad line of integration accessories. Each accessory is custom designed to compliment the highest performance Nufern amplifiers with state of the art ancilliary equipment.
A range of compatible kilowatt-class accessories are available off-the-shelf, including:
1. Stand-alone Chassis
19” Rack mounted amplifier housing containing: high power laser diode drivers, DC power supplies/turn-key safety circuitry & interlocks, Ethernet interface, input: 208VAC/30A.
Windows Based GUI Control Software included.
2. Linewidth Broadening Units, 19” Rack Mounted
Stimulated Brillouin Scattering (SBS) is one of the major limiting factors in high power amplification with a narrow linewidth seed laser required for beam combination. The linewidth broadening unit manipulates the seed to apparently increase the seed Laser linewidth in order to increase the SBS threshold which in turn enables higher power amplification.
3. Polarization Controllers, 19” Rack Mounted
The Polarization Controller unit, typically positioned between the seed laser and amplifier, enables a stable State of Polarization (SOP) to be achieved in a non-Polarization Maintaining (PM) amplifier. For instance, linearly polarized light with a stable high degree of polarization purity can be achieved (PER>17dB) using this device. An optical pick off from the output is used to generate an electrical feedback signal used in turn to control the optical servo loop.
4. Output Fiber Termination Connectors
Robust kilowatt-level “Output” connectors with a minimal impact to beam quality. (<0.1 BQ differential) designed for field serviceability as well as easier integration.
Standard units available as well as build-to-spec.
5. Packaged Seed Lasers
Low-SWAP narrow line width signal sources with integrated line width broadening unit. <50mW output. Designed to match and drive Nufern high power CW fiber amplifiers.
Nufern provides specialized fiber LIDAR/LADAR solutions suitable for terrestrial, airborne, and space borne applications. Capabilities include single-mode beam quality, pulsed and CW technology with wavelengths ranging from 1.0, 1.5, to 2.0 μm.
We are experienced in providing solutions that are widely adjustable while providing stable operation in the most challenging environments on a wide variety of platforms.
Nufern provides an expansive selection of optical fibers for applications such as laser/amplifier development, remote sensing in harsh environments, fiber optic gyroscopes (FOG), and other aerospace applications. Nufern stocks standard fibers designed to handle extreme temperature ranges, rugged duty, high hydrogen environments, and radiation exposure. For new applications Nufern offers fast-response custom fiber development.
