We demonstrate numerically that simultaneous second-harmonic generation and moderate group-velocity mismatch can lead to spontaneous nonlinear shortening during parametric amplification. As an experimental proof we present the results of twofold self-compression of signal pulses in a β-barium borate parametric amplifier pumped by either 40- or 80-fs pulses from a Ti:sapphire laser.
