Abstract

In this paper, we investigate the asymmetry of trap loss spectra of ultracold atoms during the excitation of Rydberg states. It is shown that the profile of a trap loss spectrum is affected by the density of Rydberg atoms as well as the dephasing rate of Rydberg states. The splitting of a trap loss spectrum is shown at the higher dephasing rates of Rydberg states. A three-level model, where the dephasing rates can be ascribed mainly to a random collision of Rydberg atoms, reasonably explains the experimental results.
