Abstract

The invention relates to an optical pumping device comprising: a fibre light source emitting controlled radiation having a very high transverse modal quality, with a wavelength shorter than 1000 nm; at least one element consisting of an amplifying material doped with a rare earth dopant; means for introducing a pumping light into said doped amplifying material element; and means for cooling said amplifying material. Said optical pumping device is characterised in that the pumping light is emitted by the fibre light source with an average power of higher than 2W and a modal quality characterised by an M2<5 factor.
