| Abstract: | This paper overviewed recent progress in the evolution of four different diagnostic concepts: coherent anti-stokes Raman spectroscopy,laser-induced fluorescence,vibrational Raman scattering,and hydroxyl tagging velocimetry.Techniques based on these measurement concepts can monitor a variety of parameters including temperature,species concentration,and velocity.The experimental results were given by these laser-based methods in premixed flame,solid propellant burning,and supersonic flowfields. |

| Keywords: | laser combustion diagnostics propellant supersonic flowfield |
