Doppler-free spectra of linear and circular dichroisms for the hyperfine structures of Na ${D}_{1}$ and ${D}_{2}$ lines have been obtained by means of polarization-modulated optical pumping spectroscopy. The experimental results are compared with recent theoretical calculations based on velocity-selective optical pumping in a four-level atomic system.Doppler-free spectra of linear and circular dichroisms for the hyperfine structures of Na ${D}_{1}$ and ${D}_{2}$ lines have been obtained by means of polarization-modulated optical pumping spectroscopy.
