A SPACE RUBIDIUM PULSED OPTICAL PUMPED CLOCK

The atoms of a gas (typically cesium or rubidium) confined in a cell inside a microwave cavity are excited by an optical radiation generated by a lamp or a laser (optical pumping). The pumping inverts the atomic populations of two hyperfine levels of the fundamental state that have been chosen for the transition of the clock.
