Pulse compression through noncollinear sum-frequency generation in β-barium borate crystals is investigated. With dispersion to all orders taken into account, numerical calculations, carried out in the frequency domain, were performed for input pulse durations ranging from 10 to 50 fs. Fundamental pulses of a 10-fs duration at 800 nm were compressed down to 2.5 fs while a 2.5-fs second-harmonic signal was generated.
