Abstract

We investigated the impact of an oxygen preloadingon pure-silica-core or fluorine-doped-core fiber responses to highirradiation doses (up to 1 MGy SiO ). Oxygen enrichment wasachieved through a diffusion-based technique, and the long-termpresence of O molecules was confirmed by micro-Raman experiments.Online radiation induced attenuation (RIA) experimentswere carried out in both the pristine and the O -loaded opticalfibers to investigate the differences induced by this pretreatment inthe UV and visible ranges. Contrary to results recently publishedon the positive impact of O on infrared RIA, our results reveala RIA increase with O presence. Data are analyzed in order tobetter understand the microscopic processes involved during theirradiation and to evaluate possible hardening developments.
