Ring Fiber

Everfoton's Ring Fiber is designed to meet the high power output requirements of ring lasers and variable beam profile lasers. Different from the single peak Gaussian distribution of traditional lasers, the beam is shaped through the ring fiber 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.

Excellent circular concentricityI
ndependently adjustable power between the core and ring regions
All-fiber solution to improve system reliability
Customized waveguide structure and size
