Multi-Band Laser Source for Atom Interferometry

Vescent Photonics proposes to develop a compact, low-power, environmentally robust multi-band laser system for use with the Navy’s continuous cold atomic beam interferometer. The proposed system will leverage Vescent’s expertise in developing micro-optic-based diode laser systems with low size, weight, and power (SWaP) for deployed applications in inertial sensing and cold-atom clocks. Physical Sciences Inc.’s (a subcontractor) team are experts in atom interferometry and cold-atom-based sensors, having previously demonstrated miniature vapor cells and cold-atom sources developed to support portable inertial measurement systems, and will help Vescent develop a low SWaP, environmentally robust laser system that meets the performance needs of the solicitation and yet provides a scalable, configurable architecture to meet the future needs of atom-based sensors. A program goal is to deliver standalone “plug-and-play” laser modules with integrated electronics, optics, and diode lasers that occupy less than 5% volume and consume less than 20% electrical power of available commercial frequency-stabilized laser systems. These laser modules in turn form the basis of a rack-mounted, multi-laser system that will be delivered at the successful completion of a Phase 2 program and will meet the laser performance requirements of the Navy atom interferometer while operating on a mobile platform.
