3 3 © Spectratime ® 3 Introduction on Frequency and Time Standards: Atomic Energy Levels

4 4 © Spectratime ® 4 Ground State Physics Choose atom with two ground states State selection Resonant excitation Detection

5 5 © Spectratime ® 5 What is an Atomic clock ?  Atomic resonance is intrinsically more stable than quartz local oscillator.  “Natural” atomic microwave resonance frequency is synthesized from RF LO.  Control Loop continuously steers LO frequency to atomic resonance.  RF output (10 MHz) embodies stability of atomic resonance.
