DCF-EY-6/128-PM

Description

This PM Erbium/Ytterbium co-doped fiber offers a high doping concentration and efficient energy transfer for operation in the 1.5 μm region ensuring minimum fiber length and minimum pump power. As this polarization maintaining fiber allows single-mode operation and provides excellent beam quality, it is ideal for the design of low power fiber lasers and amplifiers used in various markets such as LiDAR.

Features & Benefits
  • Single-mode operation – provides excellent beam quality
  • Highly efficient energy transfer – reduces pump power requirements
  • Low splice losses with industry-standard PM1550 fibers
  • Optimized Er/Yb core composition – reduces 1 µm parasitic emission
Applications
  • Ultrafast 1.5 µm fiber lasers
  • Eye-safe fiber lasers and amplifiers
  • LiDAR
  • Scientific
