Simultaneous effects of photo-and radio-darkening in ytterbium-doped aluminosilicate fibres

Résumé

We present original characterizations of photo-radio-darkening in ytterbium-doped silica optical fibres submitted to the simultaneous action of the pump and of an ionizing radiation. We present the interplay between both radiations, showing e.g. that the pump is able to darken or bleach the fibre depending on the ionizing dose. The photo-resistance of the fibre is shown to play a crucial role on its radio-resistance, and that photo-resistant fibres should be also radio-resistant in low dose rate conditions. All the results are thoroughly explained by a physical model presented in a separate submission by Mady et al. (this conference).
