The research progress of laser diagnosis technology of combustion field parameters is introduced. The experimental system and some experimental results of the combustion field temperature and components diagnosed by spontaneous Raman scattering, laser induced fluorescence and coherent anti-Stokes Raman scattering are given , The relative error of single flame temperature and component concentration was less than 10%. Two-dimensional OH fluorescence images of stable combustion field were obtained by planar laser-induced fluorescence and the distribution of flame two-dimensional temperature field was analyzed
