The instant invention relates to a method and an arrangement for operating a laser system for optical free space communications, in particular the generation of amplified laser light under conditions in outer space. In the process, an optical beam (72) to be amplified is conducted via a polarizing beam splitter (71) to a Faraday rotator (70) and brought from there to a neodymium crystal (68). Bymeans of reflection, appropriate diffraction and passage through a quarter-wave plate (67), a multiple passage through the neodymium crystal (68) is forced and amplification is achieved by this.
Méthode et mécanisme de fonctionnement d'un système laser pour communications optiques en espace libre, plus particulièrement la génération d'une lumière laser amplifiée dans des conditions extra-atmosphériques. Un faisceau optique (72) devant être amplifié est dirigé, au moyen d'un séparateur de faisceau polarisant (71), vers un rotateur de Faraday (70), pour ensuite être acheminé vers un cristal au néodyme (68). Grâce à la réflexion, à une diffraction appropriée et à un passage à travers une lame de mica-quart d'onde (67), un passage multiple est créé à travers le cristal au néodyme (68) et une amplification est ainsi obtenue.
