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…
Thulium-doped silica fibers with enhanced 3H4 level lifetime: modelling the devices for 800-820 nm band
Pavel Peterka, Ivan Kasik, Anirban Dhar +2
Silica-based thulium-doped fiber devices operating around 810 nm would extend the spectral range covered by high- power fiber devices. Using a comprehensive numerical model of the…
Non-Gaussian statistics and extreme waves in a nonlinear optical cavity
A. Montina, U. Bortolozzo, S. Residori +1
A unidirectional optical oscillator is built by using a liquid crystal light-valve that couples a pump beam with the modes of a nearly spherical cavity. For sufficiently high pump…
