Novel Light-shift Measurement Method with Multiple Photo Detectors for Gas-cell Based Atomic Clocks

SummaryA simple light-shift measurement method using multiple photodetectors (PDs) suitable for chip-scale atomic clocks (CSACs) and miniature atomic clocks (MACs) was proposed. This method can be used with at least two photodetectors in real-time operations. To increase the long-term frequency stabilities of CSACs and MACs, the proposed method can be used as a zero light shift detector for active light shift stabilization
