Characterization of a UV Laser Induced Fluorescence System for Detecting Atmospheric NO
UV laser fluorescence detection of trace atmospheric gases under airborne conditions has been proven to be capable of detecting atmospheric OH in the sub-part-per-trillion (ppt) range.1 This system used a Nd:YAG pumped dye laser to produce <.5 mJ at 2819Å (via SHG) in order to pump the v′=−1 manifold of the A2Σ+ excited state of OH. The resulting fluorescence was monitored at 3095Å using a high throughput optical collection scheme. Davis, et al. recently reported the requirements necessary for detecting ppt levels of the atmospheric trace gases NO, SO2 and CH2O based on their already proven OH detection system.2 Presented here are the experimental details of such a system which has detected NO at the ppt level under atmospheric conditions.
