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.

Device for a temporal shaping of the amplitude and phase of ultrashort pulses which includes:
- a birefringent waveguide (1) with a main axis (Δ) formed by a nematic liquid crystal (2) located between a photoconductor material (3) and a substrate (4);
- two transparent electrodes located one (5) between said nematic liquid crystal (2) and said substrate (4), and the other (6) so that said photoconductor material (3) is located between said other (6) and said nematic liquid crystal (2);
- and optics (7) for projecting a programmable optical mask (8) onto said photoconductor material (3) wherein said programmable optical mask (8) projected onto said photoconductor material (3) is an array (13) of black and white lines with a variable pitch.
