We show that the dressed-atom approach provides a quantitative understanding of main features radiative dipole forces (mean value, fluctuations, velocity dependence) in high-intensity limit where perturbative treatments are no longer valid. In an inhomogeneous laser beam, energies dressed states vary space, and this gives rise to dressed-state-dependent forces. Spontaneous transitions between lead multivalued instantaneous force fluctuating around mean value. The dependence is related modification, induced by atomic motion, population balance different states. corresponding modification energy associated with change fluorescence spectrum emitted atom. particular case motion standing wave investigated, two regimes identified which averaged over wavelength exhibits simple dependence. large values achievable reasonable powers pointed out view slowing down atoms
