Optical potential for laser induced dissociation

A new computational approach to molecular multiphoton dissociation is presented. Use of an optical potential allows the continuum channels to be represented as a set of pseudobound states coupled to the actual bound states of the molecule. The evolution of the system is thus amenable to the standard problem of laser induced transitions between bounds states. The long time behavior is then efficiently computed by using Floquet analysis. Results for a nonrotating diatomic are discussed.
