| Abstract: | Based on the femtosecond laser combustion diagnostic technology, the on-line measurements of temperature, velocity and component concentration in combustion flowfield can be realized. Femtosecond laser diagnostic technology is an effective diagnostic tool and has wide applications in combustion field. It plays an important role in improving combustion efficiency and reducing combustion emissions. In this paper, the authors reviewed several applications of femtosecond laser diagnostic technology in combustion field, such as femtosecond multi-photon laser-induced fluorescence (fs-MPLIF), filament-induced nonlinear spectroscopy (FINS) and femtosecond laser electronic excitation tagging velocimetry (FLEET). Then the authors summarized the development of femtosecond laser combustion diagnostic technology. On this basis, the prospect of the femtosecond laser combustion diagnostic technology in the future was analyzed and discussed, which would provide reference for the relevant researchers. |
