Ytterbium-Doped Fiber for Pulsed Lasers

DCF-YB-20/128P-08-FA-G2

Description

Specifications
Specifications

This phosphosilicate Yb-doped double-clad fiber features high and flattened pump absorption with photodarkening-free performance. This fiber is the ideal solution for a wide range of demanding high peak power pulsed fiber laser and amplifier applications in the industrial and medical markets

Features & Benefits

  • Large core diameter with high pump absorption – allows a shorter fiber length for a more compact and less expensive design while reducing non-linear effects
  • Photodarkening-free – ensures stable long-term operation
  • Wide, flat absorption from 910 nm to 970 nm – reduces pump cooling and allows 940-960 nm pumping
  • Batch-to-batch consistency in beam quality performance

Applications

  • High-energy / high peak power pulsed lasers & amplifiers for MOPA configuration
  • Laser marking and engraving
  • Medical
