G. Imeshev et al., ENGINEERABLE FEMTOSECOND PULSE SHAPING BY 2ND-HARMONIC GENERATION WITH FOURIER SYNTHETIC QUASI-PHASE-MATCHING GRATINGS, Optics letters, 23(11), 1998, pp. 864-866
We describe a pulse-shaping technique that uses second-harmonic genera
tion with Fourier synthetic quasi-phase-matching gratings. We demonstr
ate both amplitude and phase tailoring by generating a picosecond squa
relike pulse as well as trains of femtosecond pulses with a terahertz-
range repetition rate from either a compressed or a chirped pump pulse
