Abstract
Laser based spectroscopic diagnostic tools offer the exciting possibility of spatially and temporally resolved measurements of species concentrations in complex reacting gas flows of engineering interest. In our laboratory we are beginning to examine using laser induced fluorescence to measure species concentration in such devices as aircraft gas turbine combustors. The major problem associated with such measurements is the effect of quenching reactions on the fluorescence signal. To overcome this difficulty we have proposed operating in the saturation mode. For suitable systems the fluorescence signal is then no longer a function of quenching rates or laser power. Very low detectability limits appear possible.
