本文从实验上研究小型脉冲YAG激光引爆或引燃起爆药的可能性;在理论上,从激光热引爆的机理简述了激光引燃或引爆的判据。并采用大口径长程F—P型干涉仪,外调制序列脉冲激光源和高速记录装置,获得了起爆药爆轰流场和燃烧温度场的时间序列干涉图,定量计算了爆轰冲击波的传播速度。 In this paper, the possibility of detonating or igniting primer with small pulse YAG laser is studied experimentally. In theory, the criterion of laser ignition or detonation is briefly introduced from the mechanism of laser detonation. The time-series interferograms of the detonation flow field and the combustion temperature field of the detonating agent were obtained by using a large-diameter long-range F-P interferometer, an external modulated pulsed laser source and a high-speed recording device. The propagation velocity of the detonation shock wave was calculated quantitatively .
