Patent

CA 2562652

The invention relates to a device for emitting at least one tunable monomode laser beam, comprising a tunable master laser which temporarily excites at least one slave laser. The invention is characterised in that the slave laser cavity comprises a dynamic holographic medium and the operating wavelength thereof is programmed or addressed optically by means of the temporary injection of all or part of the beam originating from the master laser. The invention also relates to a device for testing optronic components comprising a plurality of light sources forming a wavelength comb that is characterised in that said source comprises a tunable master laser and a plurality of slave lasers, each comprising a dynamic holographic medium. The invention further relates to an optical addressing source for the formation of a wavelength comb.

La présente invention se rapporte à un dispositif pour l'émission d'au moins un faisceau laser monomode accordable, comprenant un laser maître accordable excitant temporairement au moins un laser esclave, caractérisé en ce que la cavité dudit laser esclave comprend un milieu holographique dynamique, et dont la longueur d'onde de fonctionnement est programmée ou adressée optiquement par l'intermédiaire de l'injection temporaire de tout ou partie du faisceau issu du laser maître. La présente invention se rapporte également à un équipement de test de composants optroniques comportant une pluralité de sources lumineuses formant un peigne de longueurs d'onde caractérisé en ce que ladite source comprend un laser maître accordable et une pluralité de lasers "esclave" comprenant chacun un milieu holographique dynamique. L'invention concerne également une source d'adressage optique pour former un peigne de longueurs d'onde.
