摘　　要：掺稀土光纤是光纤激光器的基础,而掺杂光纤的光子暗化是影响激光输出功率稳定性的重要因素。综述了光子暗化的产生机理、光子暗化对光纤激光器的影响及其抑制方法,旨在为相关研究提供参考。Rare-earth doped fibers are the foundation of fiber lasers while the photodarkening of doped fibers is a significant factor which is harmful to the stability of laser output power. In this paper, we review the mechanics of photodarkening, and the influence of photodarkening on the fiber lasers, as well as all kinds of methods which can mitigate the photodarkening effects in the doped fiber, with the aim of providing useful information for the related research.
