摘要

We have recently shown that the photodarkening (PD) resistivity in Yb/Al-doped fibers can be greatly improved by adding cerium (Ce) to the core glass composition. We are now further investigating the laser performance and long term stability of Yb/Ce/Al fibers in high inversion applications such as 980nm lasers and amplifiers. Our objective is to study the limitations of Yb/Ce/Al fibers and elaborate on their potential of becoming the next generation of fibers for high power fiber lasers and amplifiers.
