Abstract
One embodiment includes an electrometer system that includes a sensor cell and a probe laser to generate a probe beam directed through the sensor cell in a first direction and exiting the sensor cell as a detection beam. The system also includes a coupling laser to generate a coupling beam directed through the sensor cell collinearly and anti-parallel with the probe beam. The system also includes a reference signal generator configured to generate a reference signal having a predetermined polarization and a predetermined frequency through the sensor cell. The system further includes a detection system configured to monitor the detection beam to determine a frequency and a vector component of an external signal based on an intensity of the detection beam and based on the predetermined polarization and the predetermined frequency of the reference signal.
