New approach to the study of the spontaneous emission of an atomic system driven by a strong light field is developed. This approach is based on the accurate consideration of quantum system interaction with vacuum quantized field modes in the first order of perturbation theory, while the strong light field is considered classically. The proposed approach is applied to study the dynamics of field-driven atomic systems. Among them are Rabi oscillations in two-level system, resonant and nonresonant Raman and Rayleigh scattering, interference stabilization of Rydberg atoms. It is demonstrated that analyzing the spontaneous emission allows to study the specific features of quantum systems dressed by the field.
