We have theoretically investigated the phase dependence of high-harmonic generation with few-cycle laser pulses. We performed the analysis by solving the coupled evolution equations for the laser pulse and for the harmonic field in one space dimension. Our calculations reveal phase-dependent features in the cutoff region, such as a phase-dependent shift of the cutoff, that are preserved during propagation.
