Optical fields are used to probe electronic state transitions, but they can also be used as a probe of ground state transitions. Several novel features of ground state spectroscopy will be explored. After a brief review of conventional pump-probe spectroscopy, I will discuss the analogous pump-probe line shapes for ground state spectroscopy. New interference phenomena will be seen to emerge. The inclusion of atomic recoil opens a new range of phenomena. Recoil-induced resonances in ground state spectroscopy and their relation to the collective atomic recoil laser (CARL) will be described. Methods for producing sub wavelength matter wave gratings using ground state spectroscopy will also be discussed.
