Nonperturbative Treatment of Molecule-Radiation Interactions — A Coupled Equations Approach

摘要: Traditional molecular spectroscopy is interpreted usually in terms of perturbative treatments matter-radiation interactions. In such approximations, radiative transitions are visualized as between unperturbed eigenstates, i.e., free states. With present laser intensities (I > 1010 W/cm2), one can question the validity approximations. atomic spectroscopy, multiphoton and nonlinear effects have been considered dressed atom picture [1–2]. The basic idea this model that total energy system, field plus atom, must be conserved. eigenstates time independent Schroedinger equation for system therefore proper states, to used describe evolution system. simple two level leads prediction optical Stark which has observed experimentally [3–5].
