Fully Integrated Low Size, Weight, and Power (SWaP) and Cost Magnetometers for Air and In-Water Anti-Submarine Warfare (ASW)

We propose to develop the next generation of scalar atomic magnetometers with superior performance and lower size, weight, and power consumption (SWaP) than is presently available on the market. Our design leverages recent developments in the field of ultra-high sensitivity atomic magnetometers, incorporating multi-pass vapor cells and quantum non-demolition measurements to realize sensitivity in the range of 1-10 fT per root Hz and bandwidth in excess of 1 kHz. Vapor cell and all supporting lasers and electronics will be contained within a volume less than 100 cubic centimeters with less than 1 W total power consumption. To minimize magnetic interference between sensors in high order gradiometer applications, spin coherences will be driven by modulated light.
