| 简介 |
A special optical fiber for a high-output fiber laser is provided to secure excellent beam characteristic and high output and to apply to the entire industrial field utilizing a laser marker, an LCD(Liquid Crystal Display) processing device, and cutting, welding, and boring. A special optical fiber for a high-output fiber laser is composed of a dopant-doped core(100) for applying the characteristic of the laser to the optical fiber; a first cladding(110) for surrounding the core and having a refractive index lower than that of the core; and a second cladding(120) for surrounding the first cladding and having a refractive index lower than that of the first cladding. Dopant(101) is at least one selected from a group comprising a rare-earth element and metal particles. |
