1.	Somesfalean, Gabriel, et al. (författare) Long-path monitoring of NO2 with a 635 nm diode laser using frequency-modulation spectroscopy 2005 Ingår i: Applied Optics. - 2155-3165. ; 44:24, s. 5148-5151 Tidskriftsartikel (refereegranskat)abstract In situ monitoring of traffic-generated nitrogen dioxide (NO2) emissions using long-path absorption spectroscopy is reported. High-sensitivity detection of NO2 is achieved by employing two-tone frequencymodulation spectroscopy at a visible absorption band using a tunable high-power diode laser operated around 635 nm. A real-time absorption spectrometer is accomplished by repetitively applying a rectangular current pulse to the diode-laser operating current, allowing detection of isolated NO2 absorption lines. A detection limit of 10 mu g/m(3) for NO2 at atmospheric pressure using a 160 m absorption path is demonstrated. Continuous monitoring of NO2 over a road intersection at peak traffic is performed.
