Abstract

The probe absorption spectra in single and multiple tripod systems formed when a weak σ polarized pump and a tunable π polarized probe interact with a Zeeman split Fg→Fe=Fg-1 atomic transition are characterized by two interfering stimulated Raman features separated by an electromagnetically induced absorption (EIA) peak at the line center. These Raman features can appear as either sharp stimulated emission peaks or electromagnetically induced transparency windows. In the multitripod systems, the EIA and stimulated emission peaks derive from the combined effects of interference between the stimulated Raman features and transfer of coherence from the excited to ground states.
