Abstract
We observed the transient oscillation in the spectra of electromagnetically induced transparency by rapidly sweeping the probe laser frequency. The spectra were measured with laser-cooled 87Rb atoms. We show that the amplitude of the transient oscillation decays exponentially at a rate of Ωc2/2Γ, where Ωc is the Rabi frequency of the coupling laser and Γ is the spontaneous decay rate of the excited state. Using the transient oscillation, we demonstrate a simple method to determine Ωc. This method is particularly useful with the low-intensity coupling laser.
