Abstract

It is impossible to obtain an exact description of multiphoton processes in the interaction of electromagnetic fields with atomic systems. Approximate approaches must be used to describe the physically different effects that can occur. One effect is the stepwise absorption/emission of many photons by a N-level system that evolves dynamically in between each absorption/emission. The exact solution for this non-adiabatic process has been presented in many papers.12,3 A different physical effect is described in the theories of Raman processes where the simultaneous absorption/emission of many photons is considered. These calculations involve summing over all possible arrangements of multiple photon interactions neglecting the time evolution of the system in between each absorption.4 The resulting adiabatic theory has been successful in explaining many features of Raman scattering.
