Calculation of probabilities of non-resonant transitions in an intense laser field using the first-order magnus approximation in an intermediate representation

The multiphoton dissociation of a diatomic molecule under multilaser fields is studied using a semiclassical description of the system. An L2 discretization of the dissociation channel is made in the framework of the optical model method. The time displacement propagator is calculated by a multistep first order Magnus treatment using an intermediate representation with respect to the laser field–molecule interaction. An application is presented with a six bound state HF model potential perturbed by two strong laser fields. Large nonlinear effects appear in this simple system revealing the high efficiency of the two mode interaction in the dissociation process from the ground state.
