Abstract
One example includes an atomic optical reference system. The system includes an optical system comprising a laser configured to generate an optical beam. The system also includes a vapor cell comprising alkali metal atoms that are stimulated in response to a modulated beam corresponding to an amplitude-modulated version of the optical beam. The system also includes a detection system configured to monitor at least one detection signal corresponding to light emitted from or absorbed by the vapor cell and to generate at least one feedback signal in response to the at least one detection signal. The system further includes a beam modulator configured to amplitude-modulate the optical beam to generate the modulated beam and to frequency shift the optical beam to generate an output beam having a stable frequency in response to the at least one feedback signal.
