Patent number: 11507025Abstract: The invention relates to a differential detection of double-modulation (DM) CPT method and a system for implementing the method of this invention. The method comprises the following steps: Generating a coherent bichromatic light, in which the polarization and the relative phase are synchronously modulated. The DM light interacts with a quantum resonance system and prepares it into a CPT state. Then the polarization of coherent bichromatic light is switched from circular polarization to linear polarization. After interacting with the CPT state prepared in the previous stage, the constructive and destructive quantum interference occur simultaneously. The polarization of the transmitted light from the quantum resonance system is converted and spatially separated. Then two CPT signals, detected by balanced photodetectors, are observed with constructive and destructive interference respectively.Type: GrantFiled: April 1, 2021Date of Patent: November 22, 2022Assignee: National Time Service Center (NTSC), Chinese Academy of Science (CAS)Inventors: Enxue Yun, Qinglin Li, Qiang Hao, Guobin Liu, Yuping Gao, Shougang Zhang

Patent number: 11463097Abstract: The invention relates to a coherent population trapping (CPT) phase modulation and demodulation method and a system for implementing the method of this invention. The method comprises the following steps: Generating a coherent bichromatic light, in which the relative phase between the two frequency components is modulated with proper modulation depth. The phase modulated coherent bichromatic light interacts with a quantum resonance system, and prepares it alternately into two inverted CPT states. Detecting the transmitted light with a photodetector, two inverted dispersive CPT signals in two detection windows are observed. With synchronous phase demodulation, a CPT error signal is obtained, which is used for locking the local oscillator to implement a CPT atomic clock.Type: GrantFiled: March 29, 2021Date of Patent: October 4, 2022Assignee: National Time Service Center (NTSC), Chinese Academy of Science (CAS)Inventors: Enxue Yun, Qinglin Li, Qiang Hao, Guobin Liu, Yuping Gao, Shougang Zhang
