Laser cooling of atomic beams on chip for quantum sensing and metrology
Abstract
This project will develop an advanced transverse laser cooling platform utilizing microfabricatedmirrors integrated with atomic beam collimators on a chip. These advances will enable a chipscaleatomic beam sensor such as an AI gyroscope or atomic clock. These devices are thebuilding blocks for next generation precise navigation and timing (PNT) solutions that willaddress the U.S. Navys need to reduce reliance on the Global Positioning System (GPS).Toward building portable sensors that can be deployed on moving platforms such as Navysurface ships and submarines, it is known that miniaturization can lead to a loss of sensitivity.While laser cooling has been proven to be useful for macro-scale devices, the efficiency of thisprocess at the microscale has not been demonstrated and studied yet. Therefore, a key element ofour inquiry will be into multi-path laser cooling setups that can enhance the cooling for a givenlaser power and enabling the eventual miniaturization of lasers and atomic devices.
