Abstract

La présente invention concerne un système et un procédé laser optique interdépendant compact conçu pour être utilisé avec des systèmes de combinaison de faisceau de longueur d'onde (WBC) utilisant tant une WBC à axe rapide que lent. Les multiples éléments optiques ayant une fonctionnalité individuelle et interdépendante permettent de réduire et de compacter l'ensemble de l'encombrement au sol du système. De plus, les configurations intégrant le système compact décrit ici permettent un échelonnement de la puissance et de la luminosité.
