Method of stabilizing electromagnetic field strength in an atomic system |
摘要 |
Frequency stabilization of an atomic system is improved by closed loop stabilization of the power level of an atomic excitation signal. A second harmonic atomic Rabi response varies with excitation power level so that power modulation of the atomic excitation and demodulation of the second harmonic response produces a power error signal for closed loop power level control using a voltage controlled attenuator. The atomic system also includes conventional frequency stabilization closed loop control using a voltage controlled oscillator. Both power and frequency modulation of the excitation signal generate a complete atomic response from which both power and frequency error signals are generated for both power and frequency closed loop stabilization.
