Cross-correlation with spatial resolution of a quasi-direct space-to-time (QDST) pulse shaper in the far field

摘要

We present the second order cross-correlation of a quasi-direct space-to-time (QDST) pulse shaper with spatial resolution. The acquisition of the phase matching signal by a 2D-CCD camera has allowed the experimental validation that the temporal profile at the focus is controlled through the modulation of the beam profile at the entrance of a kinoform diffractive lens. An example of a temporal shaped pulse produced by the QDST pulse shaper is shown.
