We theoretically investigate how the generation of attosecond pulses
from high-order harmonics can be controlled by using a specially designed
sequence of gas jets. We demonstrate that quasi-phase-matching provided by
such a multi-jet system can be limited to a sub-femtosecond time window, while
adjusting the multi-jet structure allows tuning of the central frequency of the
generated isolated attosecond pulse.
