Two photon absorption in strong field

A shaped ultrafast pulse makes it possible to stir a quantum system and thus control a quantum process via light-matter interaction. Two photon absorption(TPA) processes between two states is one of famous systema of coherent control. We study coherent control schemes for a TPA process in a strong field. For a optimal coherent scheme to enhance TPA, strong field effects(dynamic Stark shift) has to be considered.
