Beam Delivery Fibers

The output power, beam quality and performance characteristics of many near-IR lasers has improved significantly in recent years.

This ongoing technological advance requires fibers with attributes previously required only in telecom and space born environments.

Benefiting from an environmentally controlled facility and many years of experience, the engineers at Nufern have developed a new generation of beam delivery fibers designed to address the laser industries’ ever increasing need for greater power handling capability.

Optical Benefits

  • Nufern proprietary processes yield precision diameter control over very long fiber lengths resulting in the lowest level of fiber induced beam perturbation
  • Pure silica core technology results in high damage resistance and very low attenuation in the 800 nm to 1600 nm power transmission band

Optical Benefits

  • Nufern ultra clean and environmentally controlled draw room yields the most pristine glass/polymer boundary eliminating “hot spots” and point sources of thermal failure
  • Optical silicone free buffer technology uses Nufern proprietary fluoro-acrylate coating developed for the fiber laser market

Mechanical Benefits

  • Nufern process equipment is controlled by proprietary operating software that yields extremely high strength, highest fatigue failure resistant glass necessary for durable final products.

Mechanical Benefits

  • 100% prooftest and clean room processing yields high-strength, long-life fibers suitable for use even in harsh mechanical environments.
  • Tight process control parameters & specifications result in a minimum lot-to-lot variability, yielding lowest cost termination.

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.
