Abstract
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. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
