Abstract:
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.
