1.	Kaldvee, Billy, et al. (författare) Highly range-resolved ammonia detection using near-field picosecond differential absorption lidar 2012 Ingår i: Optics Express. - 1094-4087. ; 20:18, s. 20688-20697 Tidskriftsartikel (refereegranskat)abstract Ammonia detection is highly relevant for combustion in boilers and furnaces since NH3 is able to suppress nitric oxide levels by catalytic as well as non-catalytic reduction. The mixing of ammonia with flue gases is an important parameter to obtain efficient non-catalytic reduction. In this paper picosecond DIAL was used for range-resolved, single ended, NH3 detection, utilizing a tunable picosecond laser source. The absorption spectrum of the A(v(2) = 1)-> X(v(2) = 0) band was recorded and 212.2 and 214.5 nm was selected as the on-and off-resonance wavelength, respectively. One-dimensional concentration profiles with various NH3 concentration distributions are presented. The detection limit was found to be 40 ppm with a spatial resolution of 16 cm.
