Paper Abstract

Molecules in intense fields (I ≥ 109 W/cm2) cannot be treated by perturbative methods. We have developed nonperturbative methods to calculate multiphoton cross sections in molecules based on the coupled equations of quantum collision theory. This enables us to include bound and continuum states, and to bridge the weak field (classical spectroscopy) and strong field (laser induced phenomena) cases. In particular, in the case of diatomic molecules, one can show that strong fields will induce new bound states which can drastically influence photodissociation cross sections. Examples will be presented of calculayions of two photon and three photon effects in intense fields where perturbative approaches no longer apply.
