AB We present the isolation of single attosecond pulses for multi-cycle and few-cyclelaser pulses from high harmonic generation in overdense plasmas, calculated with particle-incellsimulations. By the combination of two laser pulses of equal amplitude and a small frequencyshift between them, we demonstrate that it is possible to shorten the region in which thelaser pulse is most intense, therefore restricting the generation of high harmonic orders in theform of attosecond pulses to a narrower time window. The creation of this window is achieveddue to the combination of the laser pulse envelope and the slow oscillating wave obtained fromthe coherent sum of the two pulses. A parametric scan, performed with particle-in-cell simulations,reveals how the pulse isolation behaves for different input laser pulse lengths and whichare the optimal frequency shifts between the two laser pulses in each case, giving the conditionsfor having a good isolation of an attosecond pulse when working with laser-plasma interactionin overdense targets.
