Erbium/Ytterbium Doped Fibers

Overview

Exail develops a full range of erbium/ytterbium co-doped optical fibers for high-power CW and pulsed fiber amplifiers and lasers at 1.5 µm. Optimized for power scaling, the fibers add high brightness single-mode cores and low parasitic emission to double-clad, all-glass double-clad and triple-clad designs.

Key features

• High efficiency
• High and consistent pump absorption
• High brightness single-mode core
• Low background losses
• Large mode area with low NA
• Low 1 µm parasitic emission
• Double-clad, all-glass double-clad and triple-clad designs

Specifications

• Operation band: 1.5 µm
• Designs: double clad, all-glass double clad, triple clad

Applications

• High-power CW fiber lasers
• Pulsed fiber amplifiers
• Power scaling of 1.5 µm systems
