Composite optical bench

A method comprising:

• configuring one or more beam array sources on a first housing;
• fabricating one or more beam-specific optics on one or more second housings;
• fabricating one or more optional global optics on one or more third housings;
• positioning the one or more second housings and the one or more third housings after the first housing;
• and
• aligning the first housing, the one or more second housings, and the one or more third housings using:
• an axial alignment configuration defining axial separation of elements hosted by the first housing, the one or more second housings, and the one or more third housings;
• and
• a radial alignment configuration of optical components including the one or more beam array sources, the one or more beam-specific optics, and the one or more optional global optics.

A system comprising:

• an atomic particle confinement apparatus;
• and
• a composite optical bench assembly comprising:
• one or more beam array sources hosted by a first housing;
• one or more beam-specific optics hosted by one or more second housings;
• and
• one or more optional global optics hosted by one or more third housings,
• wherein the first housing, the one or more second housings, and the one or more third housings are aligned using:
• an axial alignment configuration defining axial separation of elements hosted by the first housing, the one or more second housings, and the one or more third housings;
• and
• a radial alignment configuration of optical components including the one or more beam array sources, the one or more beam-specific optics, and the one or more optional global optics, and
• wherein the one or more second housings and the one or more third housings are positioned after the first housing, and wherein the one or more second housings and the one or more third housings are variously positioned.
