In principle, the temporal beating of superposed high harmonics obtained by focusing a femtosecond laser pulse in a gas jet can produce a train of very short intensity spikes, depending on the relative phases of the harmonics. We present a method to measure such phases through two-photon, two-color photoionization. We found that the harmonics are Locked in phase and form a train of 250-attosecond pulses in the time domain, Harmonic generation may be a promising source for attosecond time-resolved measurements.
