Batch-Fabricated Vacuum Cell with Diffractive Optics for Miniaturized Atomic Sensors

The patent replaces traditional mechanical machining processes with batch fabrication techniques. Multiple vacuum chambers are fabricated simultaneously using deposition and bonding processes rather than individual mechanical machining, dramatically increasing manufacturing throughput while maintaining precision requirements.

The patent combines multiple fabrication steps into integrated batch processes. Multiple chambers are fabricated, sealed, and equipped with optics simultaneously in a single batch operation, rather than processing each chamber individually through separate machining operations.

The patent replaces expensive, time-consuming mechanical machining with more efficient batch fabrication techniques including deposition and bonding processes, reducing both time and cost while maintaining the required manufacturing precision for vacuum chambers and optical mounts.

The patent changes the fabrication parameters from individual mechanical machining operations to batch chemical and physical processes, fundamentally altering how the vacuum chambers are created to achieve both precision and cost-effectiveness simultaneously.

The patent uses folded optical paths that extend in three-dimensional space within the compact chamber, allowing long optical paths for atom trapping and cooling to fit within a small sensor volume by utilizing spatial folding rather than linear extension.

The patent nests multiple optical components and folded beam paths within the compact vacuum chamber volume, arranging optics and optical paths in a nested configuration that maximizes the use of available space while maintaining atom trapping effectiveness.
