Claim Text:
1. A physics package of an atomic sensor, the physics package comprising: a plurality of panes of optically transparent material enclosing a vacuum chamber, wherein the plurality of panes are fixedly attached together to form a hermetically sealed container defining the vacuum chamber therein; one or more wedges attached to an external surface of one or more of the panes; at least one of a light source, photodetector, or mirror attached to the one or more wedges, the light source configured to generate an input light beam for the vacuum chamber, the photodetector configured to detect an output light beam from the vacuum chamber, and the mirror configured to reflect a light beam from the vacuum chamber back into the vacuum chamber; wherein the one or more wedges are configured to oriente such a light source, photodetector, or mirror such that a respective light beam corresponding thereto transmits through a corresponding pane at an acute angle with respect to the corresponding pane; and wherein the at least one of a light source, photodetector, or mirror, and the one or more wedges is oriented such that one or more beams of light enter the vacuum chamber and are reflected to form at least three light paths that cross within the vacuum chamber.
