摘要：

Molecular hydrogen loading and a subsequent 193-nm ultraviolet (UV) irradiation influence on the gain properties of Er3+-doped core silica optical fibers are demonstrated in this work. The dynamics of photoinduced changes' formation and subsequent dissociation in this fiber type is demonstrated. H-2 loading results in less than a 10% fiber-gain decrease, whereas subsequent UV irradiation results in almost twice the gain degradation. Furthermore, UV-induced defects partially dissociate under the influence of 976-nm pump radiation. At least two independent types of gain degradation mechanisms of H-2-loaded active fiber under the influence of UV irradiation are shown. (C) 2019 Optical Society of America
