摘要
A novel Ramsey-type resonance signal is observed by using a simple microwave cylindrical cavity in a diode laser-pumped rubidium atomic clock. Its linewidth is 1.1 kHz. The signal lineshapes depend on the modal profile of the microwave magnetic field inside the cavity. The lineshapes are reproduced by numerical calculation. Conditions to achieve the maximum frequency discrimination sensitivity are derived by the theoretical analysis.
