Product Description
Product Introduction
Ring fiber is a type of fiber with a special structure, mainly used in high-power ring structure lasers and high attack rate beam mode tunable lasers. The energy distribution of traditional lasers is a unimodal Gaussian distribution. After coupling and shaping through a ring fiber, a Gaussian distribution in the core area and a circular laser beam surrounding the core area can be formed, which can effectively solve the problem of splashing in high-power laser welding
Application
•Laser coupling
•QBH jumper
•Laser cutting and welding
Our Advantages
Products feature
•Good geometric uniformity
•High damage threshold
•Uniform distribution of mode field intensity
