Double-cladding Ytterbium Doped Fibre (YDF)

YOFC Double-cladding Ytterbium Doped Fiber is an active optical fiber used in 1μm fiber lasers. Lasers made with the fiber cavity can be widely used in material processing, medical care, and scientific research. Fiber lasers are widely used for their lightweight, high eciency, and stability compared with traditional solid-state lasers.
Applications
  • Industry/ Medical
  • CW / Pulse fiber laser
  • High peak-power / High
  • average-power fiber laser
Characteristics
  • The large preform process guarantees precise geometric control and batch stability
  • High ytterbium-doped concentration
  • High laser slope eciency
  • Low photo-darkening
  • High reliability coating
