n° 2006REN1E001175 pagesExtraordinary high powers are nowadays available out of fiber lasers and amplifiers (» 10 kW in continuous wave regime and » 1 MW peak power in pulsed regime). Such an increase can initiate the apparition of some undesirable effects.During this thesis, we have developed and studied some high power Ytterbium doped fiber systems both in continuous wave and pulsed regimes. For this purpose, we have chosen to use the technology of double-clad fibers in association with adapted pumping techniques.Especially, we have developed an original approach that allows to efficiently amplify wavelengths of small emission cross sections. High output powers, in continuous wave regime, have been achieved experimentally and these result...
