Ring Core Fiber

Ring Core Fiber

The Ring Core Fiber is a specially structured optical fiber primarily used in high-power ring-structured lasers and high-power lasers with adjustable beam modes. Traditional lasers have a single-peak Gaussian energy distribution. After coupling and beam shaping through a ring core fiber, it can form a circular laser beam with a Gaussian distribution in the core region surrounded by the ring. This effectively solves the problem of spatter during high-power laser welding.

Product features：Good geometric uniformity；High damage threshold；Uniform mode field intensity distribution

Part Number：MP-SI14/40-12/100/120-12/360/540

Application area：Laser coupling | QBH patch cords (jumpers) | Laser cutting, welding
