用双波长马赫-曾德尔干涉法和激光阴影法研究了激光爆轰波的传播。为了研究激光爆轰波的终止机理，本文采用楔形喷管进行了准一维传播，因为侧向膨胀对激光爆轰波的终止条件有很大影响。我们还研究了气体形式的依赖性; N2和O2。结果表明，O2中爆轰波阵面的速度比N2中快。在O2中的电子密度分布的峰值高于在N2中的电子密度分布的峰值。此外，当位置接近目标壁时，该分布趋于增加。这一结果在二维情况下从未被观察到。
Propagation of a laser detonation wave was studied by two-wavelength Mach-Zehnder interferometry and laser-shadowgraph. To investigate the termination mechanism of the laser detonation wave, this study used a wedge nozzle and made a quasi-one dimensional propagation because the lateral expansion greatly influenced the LSD termination condition. We also investigated the dependency of gaseous form; N2 and O2. As a result, the velocity of the detonation front in O2 was faster than N2. The peak of the electron density profile in O2 was higher than that in N2. Furthermore, this distribution tends to increase when the position gets close to the target wall. This result has never been observed in two-dimensional situation.
