Abstract:
An oscillator controller for use in an atomic oscillator, comprising:(a) an excitation circuit having a discharge lamp, which produces a light beam by energizing said discharge lamp, the light beam being for use in pumping atoms; and (b) a circuit parameter optimizer which controls at least one circuit parameter of said excitation circuit for optimal operation thereof, comprising: a start-up voltage monitor which detects whether a start-up voltage of said excitation circuit is reached, thus producing a voltage monitoring signal, a light amount monitor which receives a resonance detection signal to check the amount of light before and after the rubidium lamp lights up, thus producing a light amount monitoring signal, and a bias voltage selector which selects a bias voltage for use in said excitation circuit, based on the voltage monitoring signal and light amount monitoring signal.
