Abstract
A characteristic feature in strong-field multi-photon ionization processes is the so-called Autler-Townes Doublet [1] that occurs due to the transient splitting of atomic energy levels in the
electric field of the laser pulse. Preliminary studies [2] revealed that the shape of this doublet
structure can be strongly dependent on the details of the pulse structure. This dependence is not only surprising, but may also be a limiting factor on the ability of calibrating absolute laser
intensities [3].
