摘要：

Autler-Townes (AT) splitting is observed in ultracold cesium Rydberg gases. Frequency and power of the laser field coupling 6S(1/2) and 6P(3/2) levels are tuned to influence the population redistribution of 6P(3/2) and nS levels excited by another light. The profile of AT spectroscopy is measured experimentally and compared with the theoretical simulation considering the estimated large dephasing rates caused by interaction between Rydberg atoms, which demonstrates that splitting and profile of AT spectra are strongly dependent on the interaction between Rydberg atoms. Rabi frequency of the coupling laser and transition dipole moment of 6S(1/2). 6P(3/2) are deduced via fitting the measured space variation of two splitting peaks, which is consistent with theoretical calculations.
