Title (EN) FIBER-LASER PUMPED CRYSTAL-LASER
(FR) LASER À CRISTAL POMPÉ PAR LASER À FIBRE
Abstract:
(EN) An apparatus for generating and amplifying laser beams at approximately 1 micrometer wavelength is disclosed. The apparatus includes an ytterbium-doped gain-crystal pumped by an ytterbium fiber-laser. The fiber-laser enables a pump wavelength to be selected that minimizes heating of the gain-crystal. The apparatus can be configured for generating and amplifying ultra- fast pulses, utilizing the gain-bandwidth of ytterbium-doped gain-crystals.
(FR) L'invention porte sur un appareil destiné à générer et amplifier des faisceaux laser à une longueur d'onde d'environ 1 micromètre. L'appareil comprend un cristal de gain dopé à l'ytterbium pompé par un laser à fibre d'ytterbium. Le laser à fibre permet de sélectionner une longueur d'onde de pompage qui réduit au minimum l'échauffement du cristal de gain. L'appareil peut être configuré pour générer et amplifier des impulsions ultra-rapides, à l'aide du gain-largeur de bande de cristaux de gain dopés à l'ytterbium.
