An ionization probe and measurement procedures are developed to permit accurate NO density measurements with good spatial and temporal resolution and with the high sensitivity and good discrimination inherent in resonance-enhanced multiple-photon ionization processes. The use of NO as a calibration standard for density measurements of other molecules and combustion radicals is discussed.
