  • Symmetric out-of-plane configurations of diffractive gratings and method
    Patent number: 10594106
    Abstract: 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.
    Type: Grant
