Title: Method Of Minimizing The Short-Term Frequency Instability Of Laser-Pumped Atomic Clocks

Abstract: The invention proposes a method of optimizing the performance of laser-pumped atomic frequency references with respect to the laser detuning and other operating parameters. The invention establishes that the frequency reference short-term instability will be minimized when (a) the laser frequency is tuned nominally a few tens of MHz away from the center of the atomic absorption line; and (b) the external oscillator lock modulation frequency is set either far below or far above the inverse of the optical pumping time of the atoms. The exact parameters for the optimization depend on the particular experimental situation and can be roughly calculated using a theory developed to simulate the clock performance.
