Abstract
In an atomic oscillator of an optical pumping system, a slot line resonator, as a microwave resonator, is arranged in a portion where atoms are excited. The slot line resonator forms a microstrip line inputting microwaves so as to be orthogonal to a slot line with a dielectric substrate being sandwiched therebetween. A container in which the atoms are enclosed is mounted on the slot line resonator, and the slot line resonator and the container are covered with a metallic case having a pumping light passage hole and a photo element.
