Fluctuations of flow parameters in a jet are generated in the shear layer of the jet boundary as the backpressure is increased. To investigate fluctuations, it is desirable to perform experiments with nonintrusive diagnostic methods. In the present experiments, the laser-induced fluorescence method was used to measure the fluctuations of a low-density axisymmetric argon jet with high spatial and temporal resolution. With this technique, the critical Reynolds number above which fluctuations were generated in the shear layer was obtained, and the fluctuation distribution of the fluorescence intensity in the jet was also clarified.
