Gain As Configurable Disorder-Adaptive Pumping for Control of Multimode Fiber Amplifiers and Lasers
Tom Sperber, Vincent Billault, Bernard Dussardier +2
Media featuring both optical gain and disorder, such as random lasers, represent formidable challenges as subjects of research due to the high complexity of the light propagation w…
Steady photo-darkening of thulium alumino-silicate fibers pumped at : Quantitative effect of lanthanum, cerium and thulium
Jean-François Lupi, Manuel Vermillac, Wilfried Blanc +4
By pumping thulium-doped silica-based fibers at 1.07~μm, rapid generation of absorbing centers leads to photo-induced attenuation (PIA). This detrimental effect prevents exploiting…
Formation and applications of nanoparticles in silica optical fibers
Wilfried Blanc, Bernard Dussardier
Optical fibers are the basis for applications that have grown considerably in recent years (telecommunications, sensors, fiber lasers, etc). Despite undeniable successes, it is nec…
Chromium-doped silica optical fibres : influence of the core composition on the Cr oxidation states and crystal field
Valérie Felice, Bernard Dussardier, Julian K. Jones +2
We have made chromium-doped, silica-based preforms and optical fibres by Modified Chemical Vapour Deposition and have studied the influence of the chemical composition of the doped…
Erbium-doped nanoparticles in silica-based optical fibres
Wilfried Blanc, Valérie Mauroy, Bernard Dussardier
Developing of new rare-earth (RE)-doped optical fibres for power amplifiers and lasers requires continuous improvements in the fibre spectroscopic properties (like shape and width…
Coherent combining in an Yb doped double core fiber laser
Johan Boullet, David Sabourdy, Agnès Desfarges-Berthelemot +5
Coherent combining is demonstrated in a clad pumped Yb doped double core fiber laser. A slope efficiency of more than 70 % is achieved with 96 % of the total output power on the fu…
