Title
(EN) SYMMETRIC OUT-OF-PLANE DIFFRACTIVE GRATINGS AND METHOD
(FR) RÉSEAUX DE DIFFRACTION SYMÉTRIQUES HORS PLAN ET PROCÉDÉ
Abstract
(EN)
Grating pair architectures used for short pulse stretching, compression and pulse shaping are enabled for use at arbitrary use angles without inducing spatial frequency chirp. These symmetric out-of-plane diffractive grating arrangements are capable of adding or removing spatial, temporal and angular chirp at any incidence angle.
(FR)
Des architectures de paires de réseaux utilisées pour l'étirage, la compression et la mise en forme d'impulsions courtes sont activées pour être utilisées à des angles d'utilisation arbitraires sans induire de fluctuation de fréquence spatiale. Ces agencements de réseau de diffraction hors plan symétriques sont capables d'ajouter ou de supprimer une fluctuation de longueur d'onde spatiale, temporelle et angulaire à n'importe quel angle d'incidence.
