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

\Ye 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 N , to single-pulse, broad-band arraydetector registration of less abundant species is made. The CARS, BOXCARS 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.
