Abstract

We describe a pulse-shaping technique that uses second-harmonic generation with Fourier synthetic quasi-phase-matching gratings. We demonstrate both amplitude and phase tailoring by generating a picosecond squarelike pulse as well as trains of femtosecond pulses with a terahertz-range repetition rate from either a compressed or a chirped pump pulse.

Spectra of the shaped pulses: Traces (a), (b), and (c) correspond to traces (a), (b), and (c) of Fig.  2. Spectrum (d) was obtained with a single uniform gating segment whose acceptance bandwidth was broader than the bandwidth of the pump pulse.
