Abstract
A device for the temporal shaping of the amplitude and phase of ultrashort pulses, includes: —a birefringent waveguide 1 of main axis Δ consisting of a nematic liquid crystal 2 located between a photoconductive material 3 and a substrate 4, —two transparent electrodes, one of which 5 is located between the nematic liquid crystal 2 and the substrate 4, and the other 6 such that the photoconductive material 3 is located between the other electrode 6 and the nematic liquid crystal 2, and —projection optics 7 for projecting a programmable optical mask 8 onto the photoconductive material 3.
