Erbium/Ytterbium co-doped double-clad fiber

DCF-EY-16/128-18

Description

Specifications
Specifications

This Erbium/Ytterbium co-doped double-clad fiber features a large mode area and high doping concentration, which are key parameters for the development of eye-safe high-power fiber lasers. The DCF-EY-16/128-18’s high slope efficiency makes this fiber ideal for the design of high-power/peak power eye-safe pulsed fiber lasers and amplifiers for LiDAR applications.

Features & Benefits

  • High doping concentration – provides highly efficient energy transfer, minimizing pump power requirements
  • Large mode area and high absorption – minimize fiber length and reduce nonlinearities
  • High slope efficiency
  • Optimized Er/Yb core composition – reduces 1 µm parasitic emission

Applications

  • Eye-safe fiber lasers and amplifiers
  • High peak power pulsed fiber lasers and amplifiers
  • Sensing: LiDAR and spectroscopy
  • Scientific
