Abstract

Le fait d'utiliser des systèmes dioptriques (1, 2) qui déplacent un deuxième groupe de faisceaux laser ensemble sur un sens d'empilement par rapport à un premier groupe de faisceaux laser et qui utilisent des systèmes optiques d'alignement par transmission/réflexion (1R, 2R, 1S, 2S) permet de façonner un diagramme de faisceau laser issu des premier et deuxième groupes de faisceaux laser produits par les systèmes optiques de transmission/réflexion (1R, 2R, 1S, 2S) de telle sorte qu'il soit plus long dans le sens d'empilement des barreaux laser. Dans cette invention, on utilise des systèmes optiques séparés pour le déplacement et l'alignement, ce qui permet aux systèmes optiques individuels d'avoir des configurations simples.
