In this work, we study the angular and energy distribution of photoelectrons generated byan attosecond-pulse in the presence of a strong laser field. This kind of process is particularlyrelevant to understand attosecond streak camera experiments [1] where an intense pulse exchange many photons with the electron after it has been ionized by a weaker and shorter pulse. The duration of the attosecond pulse, the shape of the IR streaking field and the time delay between them are the three main parameters that rule the mea-surements. Henceforth, finding a reliable theory allows to reconstruct some of this features from the available data.
