DCF-YB-12/128P-FA

Description

This phosphosilicate Yb-doped double-clad fiber offers high doping concentrations and high QCE values that ensure minimum fiber length, minimum pump power and reduced non-linearities. With all the benefits that phosphosilicate fibers have to offer, such as high energy saturation and no photodarkening, it is the perfect solution for a wide range of demanding 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
  • Wide, flat absorption from 910 nm to 970 nm – reduces pump cooling and allows 940-960 nm pumping
  • Low splice loss with standard fiber such as HI1060
Applications
  • Pulsed fiber lasers: gain media in pre-amplifiers or low power amplifiers for MOPA configuration
  • Material processing: laser marking, laser engraving, micromachining and welding
  • Medical
