Abstract: We present experimental and numerical results concerning the absorption properties of sodium vapor at moderate densities strongly driven by a pump field in the presence of a very low-intensity probe field and develop a three-level model for saturated absorption to better describe the hyperfine structure of the D-1 line. We show that this model is sufficient to explain our experimental results, and therefore conclude that recoil-induced gratings, in this configuration, are expected at higher pump and probe intensities.
