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

We investigated photodarkening loss evolution and its reduction in Yb 3+ doped aluminosilicate fibers utilizing 633 nm light irradiation. We demonstrate the final photobleaching value is intensity dependent, but the percentage of photodarkening reduc

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

In this work, the influence of photodarkening (PD) and photobleaching (PB) on the lasing features of the ytterbium-doped aluminosilicate fiber lasers is examined. Simultaneous PD and PB with 633 nm irradiation was monitored at the lasing wavelength o

A compact second-order Stokes Brillouin fiber laser made of microstructured chalcogenide fiber is reported for the first time. This laser required very low pump power for Stokes conversion: 6 mW for first order lasing and only 30 mW for second order
