Sections 13-3 and 14-4 analyze spontaneous emission from an atom interacting with the vacuum electromagnetic field. The present chapter studies the spontaneous emission of an atom irradiated by a continuous, monochromatic field. This emission is called resonance fluorescence. We compute its spectrum, which is given in steady state by the Fourier transform of the first-order correlation function of the field. We also discuss the phenomenon of photon antibunching, a purely quantum-mechanical effect described by the intensity correlation function of the emitted light. This chapter is an application of the general methods of Chap. 14 and illustrates the use of the quantum regression theorem in a central problem of quantum optics. It also establishes the connection between resonance fluorescence and the semiclassical probe absorption studies of Chap. 8, and lays the foundations for studying the generation of squeezed states by resonance fluorescence and four-wave mixing in Chap. 18.
