Temporal profiles of the attosecond pulses generated from H atom: the black dotted curve describes the temporal profiles by superposing the harmonics from 40^th to 60^th order in a 800-nm fundamental laser field (5 fs); the red solid curve describes the temporal profiles by superposing the harmonics from 75^th to 95^th order in a 800-nm fundamental laser field combined with a THz field (5 fs/800 nm, 16 fs/4800 nm).
