Abrégé
(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.
