Next Generation Coating Technology

Double-Clad fibers with polymer optical coatings are used in lasers, amplifiers, and many other fiber optic applications. Fielded applications require a new and broad tolerance to storage and deployment conditions typically involving humid and warm environments where previous generations of coatings were subject to premature degradation and failure.

Nufern has developed a new material which demonstrates far superior environmental performance (several orders of magnitude) aiding in the development of deployment conditions that avoid the need to hermetically seal or pot apparatus containing this new generation of fiber.

Optical Benefits

  • High NA >0.46 better enables high power cladding pumped fiber laser devices
  • Compatibility with PM and non PM active and passive fibers ensures uniformity across the complete range of double-clad fibers

Optical Benefits

  • Compatible with all standard pump wavelengths for 1μm, 1.5μm and 2μm and used in all Nufern Yb, Er:Yb and Tm-doped double-clad fibers
  • NuCOAT fibers reduce cladding attenuation caused by moisture ingression over time and are available on all Nufern double-clad fibers

Mechanical Benefits

  • Compatibility with dual acrylate coating technology improves the mechanical reliability of double-clad fibers

Mechanical Benefits

  • Compatibility with current coating stripping techniques ensures ease of use in the field and uniformity with current generation of double-clad fibers
  • Extended tolerance to moisture ingression improves the lifetime of deployed fibers in the field and OH induced cladding attenuation

Nufern's Fiber Lasers

Nufern’s laser technology offers the highest in efficiency, beam quality, and lifetime performance–in packages always designed with the needs of real users in mind. With a team of leading experts in laser engineering and specialty fiber design, Nufern has long been a preferred supplier of the active fibers that power the most advanced high-power fiber lasers. Now with a family of self-contained fiber laser systems, Nufern can address the next level of integration. End users of fiber lasers will enjoy the high performance and reliability common to all Nufern lasers, combined with unprecedented ease of use.

Nufern's Fiber Amplifiers

Nufern’s fiber amplifiers offer a unique approach to optical signal gain challenges by offering stable, high peak power monolithic solutions. Polarization maintaining amplifiers from Nufern, with very high signal extinction ratios, are unmatched in performance, from low power applications to multi-stage amplifiers capable of hundreds of watts of TEM00 power. Based on 100% prooftested Nufern double-clad fiber, these packaged solutions simplify the most difficult optical amplification problems—reducing program costs, complexity, and time to completion.

NukW — Harnessing Diffraction Limited Laser Power

Building on recent success by many in deploying multimode industrial fiber lasers in defense applications Nufern has produced a family of compact high performance diffraction limited single-mode high power fiber amplifiers.

Delivered turnkey from our US operations these systems provide requisite high beam quality, high efficiency, and narrow linewidth making them ideally suited for spectral or diffraction beam combination applications.  Deployment is facilitated using a patent pending remote power head connected ~ 10m distally to the preamp and diode chassis.

Fast support is available from our 3 per week production capacity, air freight compatible rental unit, and rental access to a Nufern manned multi-unit bench at our Connecticut headquarters.

Fiber Coil Winding

With a 25 year legacy of winding all types of precision optical fiber coils, the coil winding business unit offers a team of highly experienced scientists, engineers, and winders, together capable of winding the best in optical fiber coils. Cost effective and fast winding systems allow Nufern to provide a complete range of products, from simple delay lines and payout spools to strategic quadrupole gyro coils of several kilometers in length.
