The University of Virginia was awarded a $474,886 Project Grant from the National Science Foundation Division of Chemistry on July 1, 2021 to develop a trace gas detector using cavity ring-down detection of two-photon absorption. The grant is being carried out under the Mathematical and Physical Sciences program (CFDA 47.049), which aims to promote progress in these scientific fields and strengthen the nation's scientific enterprise through increasing knowledge and enhancing understanding of major problems. As part of the three-year award concluding on June 30, 2024, the University will develop a new type of trace gas detector using an innovative cavity ring-down detection technique based on two-photon absorption to detect trace atmospheric gases at very low concentrations.
