Details Introduction

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

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
