Abstract: A device for compensating time dispersions applied to the generation of ultra-short pulses, includes: two transparent optical diffraction gratings (RA, RB), which are identical and parallel to each other, operating on the principle of the Bragg diffraction, and two identical prisms (PA, PB), placed head to tail, in the space separating the optical diffraction gratings (RA, RB), knowing that the outer faces (FeA, FeB) of the prisms are parallel to each other and form a non-zero angle (γ) with the faces of the optical diffraction gratings.
