Atomic sensor physics package with integrated transmissive and reflective portions along light paths
First Claim
1. A method of forming a block for a physics package, the method comprising:
- machining a monolithic mass of optically transparent material to form at least a portion of a vacuum sealed chamber;
machining the monolithic mass of optically transparent material to form at least a portion of a light path intersecting with the vacuum sealed chamber;
polish the monolithic mass of optically transparent material, wherein polishing includes etching a first surface at an end of the at least a portion of the light path such that the first surface is optically transparent;
machining the monolithic mass of optically transparent material to form a second surface reverse of the first surface and aligned with the portion of the light path;
polishing the second surface such that the second surface is optically transparent; and
attaching a chamber evacuation structure to a first exterior opening of the vacuum sealed chamber.

Abstract
In one embodiment, a block for a physics package of an atomic sensor is provided. The block comprises one or more sections of optically transparent material defining a vacuum sealed chamber, and including a plurality of transmissive and reflective surfaces to define a plurality of light paths intersecting the vacuum sealed chamber. The one or more sections of optically transparent material include a first monolithic section defining at least a portion of the vacuum sealed chamber. The first monolithic section includes a first portion disposed across a first light path of the plurality of light paths such that light in the first light path is incident on the first portion of the first monolithic section.
