Publikováno v: Photoniques. :40-44
Les fibres optiques microstructurées, également appelées fibres à trous ou fibres optiques à cristal photonique sont un type récent de guides de lumières originaux et performants apparues dans le milieu des années 1990. Elles se sont depuis i

Publikováno v: Photoniques. :47-50
Les fibres optiques microstructurees, apparues dans le milieu des annees 1990, sont de nouveaux guides de lumieres originaux qui donnent acces a des proprietes optiques remarquables. L’originalite premiere de ce type de fibre a ete de permettre le

Publikováno v: SPIE Proceedings.
This paper reviews and extends the work done on photodarkening by our project consortium and present our latest results on bleaching and photodarkening mitigation in fiber lasers. We shows the need for a standard set-up to avoid underestimation of ph

Evidence of photodarkening mitigation in Yb-doped fiber lasers by low power 405 nm radiation
Autor: Hrvoje Gebavi, Riccardo Piccoli, Benoit Cadier, Daniel Milanese, Stefano Taccheo, Thomas Brand, David Landais, David Mechin, Olivier Le Goffic, Laurent Lablonde, Thierry Robin, Achille Monteville
In this letter, we investigate the impact of a 405 nm radiation on photodarkening generation in Yb- doped fiber laser. Simultaneous photodarkening and photobleaching effects induced by 976 and 405 nm radiations, respectively, were investigated in a 1

Publikováno v: SPIE Proceedings.
In this study, detailed investigation of photodarkening in Yb - doped aluminosilicate fibers is reported. The cooperative luminescence loss influenced by photodarkening is measured simultaneously with 633 nm probe loss. The quadratic dependence of ph

Self-similarity of time evolution of photodarkening losses induced in Yb-doped fibers and photodarkening figure of merit
Autor: Thierry Robin, Tim Durrant, Hrvoje Gebavi, Olivier Le Goffic, Daniel Milanese, Stefano Taccheo, Achille Monteville, Benoit Cadier, David Mechin, Daniel Landais, Denis Tregoat
In this paper we report and summarize an extensive investigation of photodarkening in Yb-doped silica fibers. We made a set of similar fibers in order to cover a large Yb concentration range. The results show that once uniform inversion is reached al
