Abstract
Multiple resonances were observed on the Doppler-broadened D1 line of atomic sodium in a pump-probe spectroscopic experiment. Each of these resonances is explained in terms of simple physical processes involving a four-level atomic system or subset of this sytem. These resonances arise from various saturation effects and various atomic coherence effects. The dependence of these resonances on the pump intensity and detuning from atomic resonances is also shown. The Zeeman sublevels enhanced transmission peak while contributing to the background absorption and diminishing of other peaks.
