High power, continuous-wave ytterbium-doped fiber laser tunable from 976 to 1120 nm.

We report on a linearly-polarized, continuous-wave Ytterbium-doped fiber laser continuously tunable on the fly over an unprecedented emission bandwidth ranging from 976 nm to 1120 nm and delivering a minimum of 10 W and a maximum of 41 W. Additionally, the bandwidth of the system can be tuned from 100 pm to more than 1 nm at all wavelengths

High-power widely tunable ps source in the visible light based on four wave mixing in optimized photonic crystal fibers

We present a detailed study on the generation of widely tunable visible light through four wave mixing in specifically designed micro-structured fibers. The fiber's properties are optimized for an efficient conversion to the visible and near infrared with a combined tunability from 620 to 910 nm of a picosecond Yb-doped tunable source for biomedical applications.Initiative d'excellence de l'Université de BordeauxThe Integrated Initiative of European Laser Research Infrastructure
