- Abstract
In an $$F_{e}=0\,\leftrightarrow \,F_{g}=1$$ transition, which interacting with a weak $$\pi $$ -polarized probe field and a strong $$\sigma $$ -polarized coupling field, we obtain the controlled beating signals depending on the applied magnetic field. In this configuration, we devise a procedure of light storage and retrieval where the magnetic field is switched off in the storage stage, but the magnetic field is switched on in the retrieval stage. Therefore, the beating signals is generated in the retrieval stage, which exhibits a series of maxima and minima in intensity. In addition, we can obtain two fast optical precursors and slow beating singals when the incident probe field is a squared pulse.
