The scheme of attosecond high-order harmonic generation driven by a two-pulse laser field is proposed. Calculated results show that, not only a single attosecond x-ray pulse can be produced with two pulses, which may break the energy limitation of the few-cycle pulse, but also the intensity is even higher than that generated by a single laser pulse with the same intensity.
