Laser spectroscopic techniques for combustion diagnostics

During the last decade various laser spectroscopic techniques have shown great potential for combustion diagnostics. The largest advantages with these techniques are that they permit non-intrusive measurements with high spatial, 'temporal and spectral resolution. The most important parameters measurable are; species concentration, temperature and velocity. In the present review some developments and applications will be briefly described. This includes Laser-Induced Fluorescence, LIF, Coherent anti-Stokes Raman Scattering, CARS, and Polarization spectroscopy, PS.
