We report the automated generation of high-fidelity spatiotemporally shaped femtosecond pulses using an optically addressed, reflection-mode two-dimensional spatial light modulator. The spatial light modulator has been fully characterized. We performed spatiotemporal pulse shaping by dividing a vertically expanded input pulse into many horizontal regions, each of which was independently shaped through phase-only spectral filtering. The configuration of the imaging optics determined whether real space or wave-vector shaping was performed. We performed cross correlations of shaped waveforms by using a pulse shaper to generate variably delayed pulses, demonstrating time-resolved measurement without beam splitters or delay lines.
