| 内容記述 | Since the observation of laser breakdown plasmas in gasses was reported for the first time 1963 and the possibility of the laser-induced lighting(LIL) was proposed by L. Ball et al. in 1974, as a basic study of the LIL, the laboratory-scale experiments of discharge induction have been performed with a long gap in the atmospheric air using a high energy laser. To realize the LIL, we need to clarify the mechanism of the discharge induction and the characteristics of the plasma produced by the laser. So, we measured the electron density, the temperature and the neutral particle density in the plasma produced by the small CO2 laser by means of the laser Thomson scattering and the Rayleigh scattering method. Furthermore, we measured the 50% sparkover voltage for the plate-to-plate electrodes with a short gap and observed the discharge paths for the needle-to-needle electrodes using a CCD camera. As a result, it was found that the existence of the oxygen molecules having the powerful electron affinity greatly influenced the discharge induction because the electron density in the plasma was decreased by the electron attachment to the oxygen molecules. For the neutral particle density, the thin air region expanded rapidly to the radial direction up to 20㎲ after firing the laser, and it expanded slowly after 20㎲. On the other hand, the neutral particle density near the axis of the plasma at the focal point was getting to recover gradually to the atmospheric level; the thin air shell was made. We confirmed that the discharge paths passed through the most thin air region compared with the spatio-temporal distribution of the neutral particle density. |
