The Theory of the Optical Autler-Tonnes Effect in Sodium Including Degeneracy and Detuning
Consider an atomic system illuminated by an intense monochromatic laser field tuned to resonance between two isolated atomic levels. According to the Autler-Townes theory (1955) each of the levels will be split into a doublet, the magnitude of the splitting being proportional to the square root of the intensity of the laser field. If one of the levels is connected to a third level by a second weak laser beam, the doublet structure can be probed by monitoring the population of the third level as a function of the frequency of the weak (probe) laser. The theory of this three-level model has been discussed by several authors, two recent examples being Feneuille and Schweighofer, (1975) and Whitley and Stroud (1976).
