Abstract
Recent experiments indicate that laser radiation can have significant nonthermal effects on molecular dynamical processes occurring at a solid surface. These processes include unimolecular decomposition and desorption. It has also been suggested that the interaction with laser radiation involves multiphoton absorption. This is particularly interesting since the power density of the radiation is only 10 watts/cm2, which is orders of magnitude less than the power densities typically needed to induce multiphoton absorption in the gas phase. In an effort to understand the mechanisms for such processes and to further explore the novel area of heterogeneous catalysis with lasers, theoretical studies have been undertaken for several different types of processes occurring at a solid surface: 1) laser-stimulated surface phenomena (migration, recombination and desorption), 2) laser-controlled heterogeneous rate processes, and 3) atom-surface collisions in the presence of laser radiation. This last type includes diffractive scattering, energy transfer and collisional ionization of an adatom by a gas-phase projectile atom.
