Comparative Study of Ultra-Precise Optical Displacement Sensing Techniques: From Planetary Seismology to Geosciences Applications

Ilyes Daddi Hammou, Mathieu Feuilloy, Philippe Ménard, Alban Leleux et autres

Optical sensing technologies are increasingly pivotal in geosciences and planetary exploration, where ultra-precise displacement measurements are essential for understanding seismic activity, subsurface dynamics, and environmental monitoring. This work presents a comparative analysis of two advanced optical measurement techniques developed in parallel by …

High power neodymium-doped single-mode all-fiber laser at 922 nm using chirped tilted fiber Bragg gratings

Alban Leleux, Yiğit Ozan Aydın, William H. Bisson, A. Michaud et autres

We report the demonstration of a neodymium-doped silica all-fiber laser delivering a single-mode output power of 17.7 W at 922 nm in continuous wave operation. The system is based on an in-house developed step-index fiber, having its core co-doped with neodymium, aluminum, …

922 nm single-mode Nd-doped all-fiber laser using a chirped tilted fiber Bragg grating

Alban Leleux, Yiğit Ozan Aydın, William H. Bisson, Mathieu Gagné et autres

We present a single-mode all-fiber laser emitting 4 . 7 W at 922 nm, based on a neodymium-doped silica step-index fiber and a chirped tilted fiber Bragg grating cavity filter suppressing the competing amplified spontaneous emission at 1060 nm.

Contrôle non destructif de composites par ondes ultrasonores guidées, générées et détectées par multiéléments

Alban Leleux

Une technique de Contrôle Non Destructif (CND) a été développée, permettant la génération et la détection d’ondes de Lamb guidées le long de grandes plaques constituées de différents matériaux (métal, polymère ou composite renforcé par des fibres). Basée sur l’emploi de nombreux …
