Title
(EN) METHODS AND SYSTEMS FOR EFFICIENT SEPARATION OF POLARIZED UV LIGHT
(FR) PROCÉDÉS ET SYSTÈMES DE SÉPARATION EFFICACE DE LUMIÈRE UV POLARISÉE
Abstract
(EN)
Methods and systems are provided for separating polarized UV light. In one example, a method may include passing polarized source light through a group of at least four prisms to collimate and separate a second-harmonic generation (SHG) beam from a pump beam. The separated SHG beam may then be further passed through a spatial filter to reduce spatial distribution.

L'invention concerne des procédés et des systèmes de séparation de lumière UV polarisée. Dans un exemple, un procédé peut consister à faire passer une lumière source polarisée à travers un groupe d'au moins quatre prismes pour collimater et séparer un faisceau de générations de seconde harmonique (GSH) à partir d'un faisceau de pompage. Le faisceau GSH séparé peut ensuite être passé à travers un filtre spatial pour réduire la distribution spatiale.
