Product Description

Ytterbium Doped Fibers

1. Introduction

Ytterbium-doped fiber is a double-clad or triple-clad active optic fiber, and it can output 1μm-band high power laser. This product is mainly used in ytterbium doped fiber lasers and amplifiers, and is widely used in industrial, medical and scientific research fields with its advantages of high output beam quality and good stability. By adjusting optic fiber parameters, we can provide different sizes and shapes of ytterbium doped fibers to meet various application requirements.
