New phase and amplitude high resolution pulse shaper

We present the first realization of a femtosecond pulse shaper in phase and amplitude using two liquid crystal devices with 640 pixels, leading to a wide temporal window around 25 ps at 800 nm. Several examples illustrate the high resolution of such device. The use of a folded zero dispersion line is also successfully demonstrated.
