  • Linear time-gate method and system for ultrashort pulse characterization
    Patent number: 11415461
    Abstract: A method comprising forming a linear temporal non-stationary amplitude filter by interacting a high intensity ultrashort laser pump pulse with a photo-excitable material, focusing an ultrashort broadband laser probe pulse over the photo-excited material, acquiring a two-dimensional spectrogram and retrieving amplitudes and phases of both temporal probe pulse and linear non-stationary amplitude filter from the two-dimensional spectrogram.
    Type: Grant
    Filed: September 24, 2018
    Date of Patent: August 16, 2022
    Inventors: Philippe Lassonde, Guilmot Ernotte, Bruno E. Schmidt, François Légaré, Stéphane Petit, Jean-Christophe Delagnes, Eric Cormier, Adrien Leblanc
