NuFBG Fiber Bragg Reflector

  • Wavelength matching HR & output coupling device
  • Matched to Nufern active fibers; both SM & LMA versions stocked
  • High power handling: >30W for 8/120 gratings; >500W for 20/400 gratings

NuBUG Bench Top Fiber Termination Device

  • Large anvil for absorbing rejected heat from fiber
  • Large shield face to absorb reflected power form meter & protect fiber
  • Finger shelf for easy and repeatable loading
  • Spring loaded for fast and easy "no-tool" use

NuCOIL Coil Form & Loading Tool Kit

  • Uses the inherent straightening force generated within a bent fiber to gently but firmly contact the heat rejecting active fiber to a heat sink
  • Keeps heat rejecting coils of fiber out of thermal contact with other fibers & inhibits optical communication from wrap to wrap
  • Is easily loaded and unloaded for the benefit of experimenters

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.
