This paper presents some of the development actions performed these last years at ONERA using laser spectroscopic techniques to probe chemically reacting §ows. Techniques like laser absorption, laser induced §uorescence (LIF), and Raman scattering will be described with focus on present drawbacks as well as expectations from new laser technologies (Interband Cascade Lasers (ICL) diodes, Optical Parametrical Oscillators (OPO), frequency comb, and femto/picosecond lasers) before showing some
