Chirp control in the direct space-to-time pulse shaper.
The dispersion properties of the direct space-to-time pulse shaper are investigated for the first time to our knowledge. We demonstrate that phase-front curvature of the input spatial profile leads to a chirp in the output temporal waveform, which one can compensate for by varying the separation between the pulse-shaping lens and slit. Furthermore, the output intensity profile remains invariant as the chirp is manipulated. These properties are fundamentally different than in the well-known Fourier-transform pulse shaper.
