DCF-EY-12/130H

Description

This Erbium/Ytterbium co-doped fiber offers a high doping concentration and efficient energy transfer for operation in the 1.5 μm region. It also provides high pump absorption while maintaining a good beam quality. These features make this fiber ideal for the design of high peak power eye-safe fiber lasers and amplifiers used in sensing applications such as LiDAR.

Features & Benefits
  • High doping concentration – provides highly efficient energy transfer, minimizing pump power requirements
  • High absorption – minimizes fiber length and reduces nonlinearities
  • Optimized Er/Yb core composition – reduces 1 µm parasitic emission
Applications
  • Eye-safe fiber lasers and amplifiers
  • Sensing: LiDAR and spectroscopy
