Abstract

Design, development, and application of novel all-solid- state spectroscopic gas sensors is reported. These compact instruments employ mid-infrared difference-frequency generation in a nonlinear optical medium pumped by room- temperature semiconductor lasers, and are capable of real- time selective measurement of trace gases in ambient air with better than 1 ppb precision (part per billion, by mole fraction).
