Abstract
One embodiment includes an electrometer system. The system includes a sensor cell comprising alkali metal atoms within, and a probe laser configured to generate a probe beam, the probe beam being provided through the sensor cell. The system also includes a coupling laser configured to generate a coupling beam. The coupling beam can be provided through the sensor cell to combine with the probe beam provided through the sensor cell to provide a Rydberg energy state of the alkali metal atoms, the probe beam exiting the sensor cell as a detection beam. The system further includes a sensor control system configured to monitor the detection beam to detect an external signal based on monitoring a phase of the detection beam.
