Abstract

A method for controlling an atomic clock is described. The method includes receiving, at a processor, a request including an operational mode of multiple operational modes for the atomic clock. The atomic clock includes a local oscillator, a vapor cell, a detector, and a local oscillator controller. The vapor cell includes atoms and receives from the local oscillator a signal having a frequency. The signal causes transitions of the atoms between atomic energy states. The detector detects the transitions and provides to the local oscillator controller an error signal based on the transitions. The error signal indicates a difference between the frequency and a target frequency. The local oscillator controller controls the local oscillator based on the error signal. The processor determines, based on the operational mode, values for control parameters for the atomic clock. The atomic clock is controlled using the values of the parameters.
