Theoretical treatments of laser-induced inelastic scattering have traditionally considered (translational) free-to-free transitions. We present a treatment of laser-induced resonances (quasibound states) in molecular scattering. The main result is that large cross sections for inelastic scattering may be achieved at low radiation densities, fully exploiting the monochromaticity and tunability of lasers. A calculation is performed which models the collision of Xe and F atoms in the presence of two lasers. One laser dresses the molecular electronic states, inducing the formation of scattering resonances; the other serves as a probe, inducing transitions between resonances during the collision (energy transfer). The system finally breaks apart by stimulated emission and with an increase in translational energy (laser heating). The total scattering cross section is high (∼ 1 Å2), even though both lasers are of low intensity (less than 1 kW cm-2). Applications to spectroscopy of the transition state and to curve-switching processes are discussed. |
