The radiative corrections received by laser-dressed atomic states were analyzed using ideas from quantum electrodynamics and quantum optics. An experimental scheme based on the incoherent resonance fluorescence spectrum of the driven atom, was proposed to measure these corrections. The dominant interaction in the system was the coupling of the atom to the driving laser field which produced the atomic laser-dressed states. The results show that the calculated Lamb shift of laser-dressed atomic states is different from that obtained via conventional approximate treatments, where the perturbative quantum electrodynamic interaction is evaluated prior to the exact quantum optical coupling with the laser field.
