Abstract
One example includes an electrometer system. The system includes a sensor cell comprising alkali metal atoms within, and an optical beam system configured to provide at least one optical beam through the sensor cell to provide a first Rydberg energy state of the alkali metal atoms, the at least one optical beam exiting the sensor cell as a detection beam. The system also includes a radio frequency (RF) tuning field generator configured to generate an RF tuning signal having a tuning frequency that is equal to an energy difference between the first Rydberg energy state and a second Rydberg energy state of the alkali metal atoms. The system further includes a detection system configured to monitor the detection beam to detect an external signal having a frequency that is between the first and second Rydberg energy states.
