Abstract
We numerically study two-photon processes using a set of harmonics from a Ti:sapphire laser and, in particular, interference effects in the above-threshold ionization spectra. We compare the situation where the harmonic phases are assumed locked to the case where they have a random distribution. Suggestions for possible experiments, using realistic parameters, are discussed.Keywords
