Ammonia measurements with femtosecond laser-induced plasma spectroscopy
Femtosecond laser-induced plasma spectroscopy for in situ ammonia (NH 3 ) measurements was demonstrated in NH 3 ∕N 2 mixtures. When a femtosecond laser at 800 nm was focused at the flow field, the parent NH 3 molecules would be photolyzed to generate electronics excited NH fragments, and then indirect measurements of NH 3 could be realized by detecting the NH fluorescence (A 3 Π − X 3 Σ −
