A resonator package can comprise a microwave container which does not have to be tuned, such as an untuned waveguide, carrying an absorption cell and forming an optical path through its open end and the absorption cell and leading to a light detection means, and a microwave loop adjustably carried by the microwave container between the absorption cell and the light detection means. The microwave loop can be carried by a carrier slidably engaging a slot formed in the waveguide, and can be tuned by adjusting its position with respect to the adjacent face of the absorption cell. The resonator package can thus eliminate a microwave cavity and the need for the precise dimensions of a microwave cavity and the problems of separately tuning a microwave cavity and loop, and can permit smaller resonator assemblies without the use of dielectric loading and the use of a loop that also functions as a very simple and inexpensive microwave multiplier/mixer.
In a resonator package for an atomic frequency standard, comprising a microwave container forming a light window at one end and a connection for light detection means, and an absorption cell and microwave exciter for said absorption cell carried within said microwave container wherein the improvement comprises a microwave container that is untuned, and the microwave exciter for said absorption cell is carried by said microwave container.
A resonator package for an atomic frequency standard including a microwave container forming an optical axis and further including a microwave exciter, an absorption cell, and a light detector, said microwave container being an untuned waveguide with the light detector adjacent one end, and said microwave exciter being a microwave loop adjustably carried by the untuned, waveguide between the light detector and the absorption cell.
