Accuracy improvement of AC Stark shift microwave detection based on a “frequency ruler”
The detection accuracy of frequency shift is crucial in microwave detection based on the Rydberg atomic alternating current (AC) Stark shift effect.We design a frequency shifter system that can provide a high-precision frequency reference signal and improve the detection accuracy of frequency shift.This system utilizes acoustic-optic modulators to generate two coupling lights with a fixed frequency interval and completes double Rydberg atomic excitation.The detection accuracy of the AC Stark shift (1.33 MHz) is 6.08 times better than that of the wavelength meter-reading scheme (8.09MHz), and the minimum detectable frequency shift is improved by a factor of 3.13.
