The Department of Defense (DOD) is seeking proposals for a Small Business Innovation Research (SBIR) program focused on the topic of "Remote Magnetometry with Resonantly Enhanced Multiphoton Ionization (REMPI) Readout". The research aims to demonstrate atomic magnetometry in air using radar REMPI readout of 129Xe quantum states. The goal is to develop a method for remote magnetometry using atoms in the air at sea level. The research will involve using ultrashort pulse lasers to demonstrate REMPI in air and remotely readout the ionized electrons for a standoff magnetometry signal. The project will be conducted in two phases, with Phase I focusing on demonstrating radar REMPI detection of 129Xe using three-photon excitation in a vapor cell, and Phase II aiming to demonstrate remote magnetometry using radar REMPI readout with 129Xe in a vapor cell. The project will also explore methods to improve measurement sensitivity, increase pumping efficiency, and decrease laser energy requirements. The potential applications of this technology include trace gas detection for air quality monitoring, combustion characterization, and magnetic mapping for geophysical prospecting. The project duration and funding specifics are not provided in the document.
