Double-cladding Ytterbium Doped Fibre (YDF)

YOFC double-cladding 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, material processing, medical treatment and scientific research and other fields. 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
  • Industry/ Medical
  • High peak-power / High average-power fiber laser
Characteristics
  • Precise geometry
  • High ytterbium doped concentration
  • Low NA core, LMA designed
  • High laser slope efficiency
  • Low photo-darkening
  • High reliability coating
