Abstract

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).
