Double-clad Ytterbium Doped Fibre(YDF)
YOFC double-clad ytterbium doped fibre (YDF) is one kind of active fibre applied for 1 micrometer fibre optical amplifier and fibre laser. Laser made by fibre cavity is extensively used in areas as military, 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.
