Coherent Anti-Stokes Raman Spectroscopy (CARS) Applied in Combustion Probing

We have applied Coherent Anti-Stokes Raman Spectroscopy (CARS) for monitoring of a variety of important molecules in combustion media. A survey of different CARS techniques ranging from simple, scanning measurements of major species like N2 to single-pulse, broad-band array-detector registration of less abundant species is made. The CARS, BOX-CARS and folded BOXCARS approaches were used observing normal rotational-vibrational, as well as pure rotational spectra. Different premixed flames were used in the investigations. Special emphasis is put on simultaneous dual- (multi-) species detection using array-detector techniques.
