Asymmetry analysis of Autler-Townes doublet in the trap-loss fluorescence spectroscopy of cesium MOT with single step Rydberg excitation
X. K. Hou, Y. W. Wang, J. He +1
Autler-Townes (AT) doublet, a fundamental manifestation of quantum interference effects, serves as a critical tool for studying the dynamic behavior of Rydberg atoms. Here, we inve…
Narrow-linewidth 852-nm DBR-LD with self-injection lock based on high-fineness optical cavity filtering
Lili Hao, Rui Chang, Xiaokai Hou +2
Narrow-linewidth lasers have high spectral purity, long coherent length and low phase noise, so they have important applications in cold atom physics, quantum communication, quantu…
Autler-Townes splitting in the trap-loss fluorescence spectroscopy due to single-step direct Rydberg excitation of cesium cold atomic ensemble
Xin Wang, Xiaokai Hou, Feifei Lu +6
We experimentally investigate trap-loss spectra of the cesium 6S1/2(F=4)-71P3/2 Rydberg state by combining the cesium atomic magneto-optical trap with the narrow-linewidth, continu…
Suppression of laser beam's polarization and intensity fluctuation via a Mach-Zehnder interferometer with proper feedback
Xiaokai Hou, Shou Liu, Xin Wang +3
Long ground-Rydberg coherence lifetime is interesting for implementing high-fidelity quantum logic gates, many-body physics, and other quantum information protocols. However, the p…
Measuring the hyperfine splittings and deriving the hyperfine-interaction constants of Cesium 7D 5/2 excited state
Zerong Wang, Xiaokai Hou, Jiandong Bai +1
The measurement of Cesium (Cs) 7D5/2 excited state's hyperfine splitting intervals and hyperfine-interaction constants has been experimentally investigated based on ladder-type (85…
