    "abstract": "A theory of pump-probe spectroscopy is developed in which optical fields\ndrive two-quantum, Raman-like transitions between ground state sublevels. Three\nfields are incident on an ensemble of atoms. Two of the fields act as the pump\nfield for the two-quantum transitions. The absorption or gain of an additional\nprobe field is monitored as a function of its detuning from one of the fields\nwhich constitutes the pump field. Although the probe absorption spectrum\ndisplays features common to those found in pump-probe spectroscopy of\nsingle-quantum transitions, new interference effects are found to modify the\nspectrum. Many of these features can be explained within the context of a\ndressed atom picture.",
