摘要： 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.
