AbstractTwo-photon Laser induced fluorescence diagnostics system for atomic oxygen has been installed at the 750kW arc heated wind tunnel in JAXA in order to obtain velocity, translational temperature, and number density of atomic oxygen simultaneously. It was observed that the center of excitation wavelength was shifted in the shock layer. The Doppler shift due to the free stream velocity has a good agreement with that estimated by a simulated value. In this experiment, the translational temperature distribution could not be deduced from spectral broadening because of the overestimated laser broadening measured by a wavemeter. The laser broadening was estimated so that the range of the translational temperature in the free stream was from 500K to 1, 500K. As a result, the absolute atomic number density was obtained with a calibration technique by a reference xenon gas cell at three conditions of arc heated wind tunnel.
