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