摘要: The generation of attosecond pulses by superposition high harmonics relies on their synchronization in the emission. Our experiments low-order, plateau, and cutoff regions spectrum reveal different regimes electron dynamics determining quality. shortest are obtained combining a spectral filtering from end plateau cutoff, far-field spatial that selects single quantum path contribution to This method applies isolated as well pulse trains.
