50/100µm Core Diameter Ring Fiber

Fibercloud's ring fiber features a unique optical fiber structure, primarily used in high-power ring lasers and high-power tunable beam lasers. While conventional lasers have a single-peak Gaussian energy distribution, coupling and shaping through the ring fiber creates a Gaussian core distribution and a circular laser beam surrounding the core, effectively addressing the spatter issue associated with high-power laser welding.
