Attosecond pulse trains are produced during the production of high harmonics when a gas sample is irradiated with an intense femtosecond laser pulse. Usually the attosecond pulses are characterized in a second gas source. We show that attosecond pulses can be measured directly as they are produced by using a weak second harmonic of the driving laser, and that such a field can also be used to control...
