Abstract
A method of controlling the amplitude of the microwave signal applied to an atomic clock comprising an atomic resonator and a device for interlocking an ultra-stable oscillator in follow-up relationship with the atomic resonance, adapted to produce the signal from which the microwave signal is derived, the method consisting in transforming the amplitude of the microwave signal before its application to the atomic jet resonator according to a law such that the shape of the curve of atomic response versus the amplitude of the microwave signal be symmetrical over a wide extent about the vertical line passing through the maximum of the response.
