DCF-YB-50/400P-FAC

Description

The DCF-YB-50/400P-FAC phosphosilicate Yb-doped double-clad fiber features high and flattened pump absorption with photodarkening-free performance. Its large core diameter increases the level of energy per pulse, making this product the perfect solution for demanding high peak power pulsed 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
  • High energy level – up to 10 MJ / 100 kW @ 100 ns
  • Wide, flat absorption from 910 nm to 970 nm – reduces pump cooling and allows 940-960 nm pumping
Applications
  • High peak power MOPA pulsed lasers & amplifiers
  • Laser marking and engraving
  • Laser cleaning / Surface treatment
  • Medical
