Abstract
The visible cooperative luminescence in Ytterbium-doped optical fibres was observed using a Titanium-Sapphire infrared laser excitation (≈900nm). The evolution of this luminescence as a function of absorbed power is discussed. The optical confinement therefore enables us to observe new saturation effects which are studied for two different Ytterbium fibres.
