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.

Linear time-gate method and system for ultrashort pulse characterization

A system comprising a laser emitting an ultrashort pulse beam; and a dielectric bulk medium having a refractive index depending on intensity, the bulk medium broadening the laser beam homogeneously versus transversal spatial coordinates, and a method for compressing high energy femtosecond laser pulses, comprising propagating the laser beam inside a dielectric bulk medium having a refractive index depending on the beam intensity, the bulk medium broadening the laser beam homogeneously versus transversal spatial coordinates; and compressing a resulting broadened spectrum.

System and method for high-intensity ultrashort pulse compression

A method comprising using a pulse shaper in the spectral domain to generate multiple-color pulses directly at the output of the laser amplifier. The delay can thus be controlled directly in the spectral domain and there is no need for an optical delay line. The method allows reducing the number of optical components and insures insensitivity to alignment, vibrations and turbulence on long distance propagation and filamentation, particularly in air. The method allows programmable and tunable interaction, since the pulse shaper is able to control the laser spectral amplitude and phase.
