Abstract

The present invention discloses an atomic sensor physical package with an optically transparent pane and an external wedge. One embodiment involves physical packaging of atomic sensors. The physical package includes multiple panes of optically transparent material enclosing the vacuum chamber and one or more wedges attached to the outer surface of the one or more panes. The physical package also includes at least one of a light source, a photodetector, or a mirror attached to the one or more wedges, the light source being configured to generate an input beam for the vacuum chamber, the photodetector being configured to detect an output beam from the vacuum chamber, and the mirror is configured to reflect a beam of light from the vacuum chamber back into the vacuum chamber, wherein the wedge is configured to orient such light source, photodetector or mirror such that a corresponding light beam corresponding thereto transmits through it at an acute angle relative to the corresponding pane Corresponds to the pane.

Description

[0001] Statement Regarding Federally Sponsored Research or Development [0002] This invention was made with government support under W31P4Q-09-C-0348 awarded by DARPAW. The government has certain rights in this invention. technical field [0003] The present invention relates to atomic sensor physical packaging with optically transparent panes and external wedges. Background technique [0004] Efforts are underway to reduce the size and packaging of atomic sensors, including atomic clocks and other sensors that utilize clouds of cold atoms as sensing elements. To do this, efforts have focused on reducing the size of the physical packages used for atomic sensors. An example of a physical package is a glass block that is machined and sealed to maintain an ultra-high vacuum. In certain configurations, the glass block includes multiple faces on its exterior, and multiple angled boreholes that serve as optical paths for capturing, cooling, and manipulating the cold atomic sam...
