N2 - A new nonintrusive diagnostic technology, 'radar resonant enhanced, multiphoton ionization (REMPI),' which can provide localized measurements of both dominant and trace species with high-sensitivity and with high-selectivity, has been developed. Radar REMPI uses resonant enhanced, multiphoton ionization to ionize selected molecular species and microwave scattering to detect that ionized plasma. Ionization is generated by an m-photon multiphoton excitation step to an intermediate electronic state, followed by an n-photon multiphoton ionization process. This diagnostic can be used for detection of hazardous gases of pollutants in air, the measurement of major and minor species densities in reacting environments, and the determination of temperature. The combination of laser excitation and microwave scattering detection allows this diagnostic approach to be used for remote detection for airborne gases, for pollution measurement and for threat identification.
