Femtosecond laser-induced plasma spectroscopy for in situ ammonia (NH

mixtures. When a femtosecond laser at 800 nm was focused at the flow field, the parent NH

molecules would be photolyzed to generate electronics excited NH fragments, and then indirect measurements of NH

could be realized by detecting the NH fluorescence (A
