内容記述 | Effect of radiative transfer on a laser-absorption wave was investigated with a spectroscopic measurement and an analytical model. The model described a propagation mechanism in terms of the relation between a number of photon emission and the velocity of an ionization-wave front. From spectroscopic measurements, electron temperature was estimated to be 2 eV for 10.6 micrometer laser wavelength and 5 eV for 1.05 micrometer laser wavelength near the laser intensity-threshold for laser-supported detonation. Electron number densities of the order of (1.5-3.9) × 10(exp 24) m(exp -3) was deduced in air. Argon and air were compared at varying laser intensities, the propagation velocity of laser-absorption wave using spectroscopic study and the model was estimated to be 10(exp 3) m/s which showed a good agreement with laser-shadowgraph visualization. The results revealed that the photoionization by UV-radiation plays an important role in the laser-absorption wave propagation. | |||||
