Pulsed and CW Molecular Beam CARS Spectroscopy
The advantages of molecular beam coherent anti-stokes Raman spectroscopy include increased spectral resolution from sub-doppler linewidths, improved signal-to-noise resulting from spectral simplification due to rotational cooling upon expansion, and the possibility of studying molecular complexes generated by the expansion process. In this paper we report recent high resolution CARS studies using pulsed laser sources combined with a reliable pulsed molecular beam source and the first cw CARS measurements in a steady state high Mach number supersonic expansion.
