  • METHOD AND SYSTEM FOR MEASURING CARRIER-TO-ENVELOPE PHASE FLUCTUATIONS OF A FEMTOSECOND LASER PULSE
    Publication number: 20230028731
    Abstract: A method and a system for measuring carrier-to-envelope phase fluctuations (CEP) fluctuations of a laser field, the method comprising focusing laser pulses in a solid-state material for high harmonic generation, collecting a resulting high harmonic spectrum, and inferring a relative phase of the driving field from the high harmonic spectrum. The system comprises a source of CEP stable mid-infrared laser pulses; a CEP variation unit; a solid state medium; a detector; and first focusing optics focusing pulses generated by the source into the solid state medium and second focusing optics collecting resulting harmonics generated in the solid state medium into the detector.

  • 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.
