This invention concerns a device for optical coupling of a solid-state laser with an optical wave guide. To that effect, an anamorphotic lens system is positioned between the exit surface of the solid-state laser and the entrance surface of the optical wave guide. This lens system transforms differing apertures in the major section of the solid-state laser into essentially equal apertures at the entrance surface of the optical wave guide. The lens system consists of anamorphotic lens mounted at the exit surface and an additional lens mounted at the entrance surface. This invention also comprises a process for producing the device.
L'invention concerne un dispositif de couplage optique d'un laser à corps solide à une fibre optique. Un système de lentilles anamorphotiques est placé entre la surface de sortie du laser à corps solide et la surface d'entrée de la fibre optique. Ce système transforme différentes ouvertures pratiquées dans la section principale du laser à corps solide en des ouvertures sensiblement identiques sur la surface d'entrée de la fibre optique. Le système de lentilles est composé d'une lentille anamorphotique appliquée sur la surface de sortie et d'une autre lentille appliquée sur la surface d'entrée. L'invention concerne également un procédé de production du dispositif correspondant.
