Double-clad Ytterbium Doped Fibre(YDF)

YOFC double-clad ytterbium doped fibre (YDF) is one kind of active fibre applied for 1 micrometer fibre laser. Laser made by fibre cavity is extensively used in areas as, material processing and scientific research. Fibre laser is widely used for its advantages of lightness, efficiency and stability, which are competitively alternative to solid state laser.
Applications
  • CW/Pulse fibre laser and amplifier
  • Industry/ Medical
  • Material processing
  • Fibre laser source
Characteristics
  • Precise geometry
  • High ytterbium doped concentration
  • Low NA core, LMA designed
  • High laser slope efficiency
  • Low photo-darkening
  • High reliability coating
