Ring Fibre

YOFC Ring Fibre is designed to meet the high power output requirements of ring-structured lasers and variable beam profile lasers. Different from the single peak Gaussian distribution of traditional lasers, the beam is shaped through the ring fibre to form a Gaussian distribution laser beam in the core area and a ring laser beam around it. The parallel use of the two beams can effectively reduce the spatter of high-power laser welding.

Applications
  • High power lasers
  • Welding of new energy batteries, auto parts and electronic components
  • Domestic substitution of imported products
Characteristics
  • Excellent circular concentricity
  • Independently adjustable power between the core and ring regions
  • All-fibre solution to improve system reliability
  • Customized waveguide structure and size
