Overview
Nufern offers a comprehensive range of high-powered laser and amplifier fibers known for their performance and reliability. These fibers are suitable for various applications, including pulsed or continuous wave operations, specific mode characteristics, and single polarization.

Product Families
The product families include NuLASER, NuAMP, NuSUB, NuPOWER, EyE SAFE, NuPANDA, NuWIRE, and NuCOMM.

Key Features

• Long Life: Designed for no service in the first 20,000 hours with extreme power stability (<1% long-term drift).
• Highest Performance: High conversion efficiency, narrow linewidth, highest brightness, and easy single mode TEM00 achievement.
• Single Polarization: High extinction ratio polarized laser output, suitable for frequency conversion applications.
• Broadest Selection: Wavelengths from NIR to 2.3 µm, core and clad sizes from 4 to 700 µm, and special designs like Chiral Core and Multi-core.

Technical Specifications
The fibers feature a high numerical aperture (NA) input for broad acceptance of low brightness pump energy, which is absorbed by a rare earth ion in the core and converted into laser light. The low NA output yields a high brightness, low divergence, single mode beam.

Core Design and Wavelengths

• Single Mode: 1.0 µm, 1.5 µm, 2.0 µm
• Multimode: 1.0 µm, 1.5 µm, 2.0 µm
• Large Mode Area (LMA): 1.0 µm
• Large Flattened Mode (LFM): 1.0 µm
• Chiral Core: 1.0 µm
• Multicore: 1.0 µm

Polarization maintaining (PM) and non-PM options are available for various designs.
