摘要
介绍脉冲YAG激光引爆点火药的实验结果,如点火药在调Q和自由振荡YAG激光脉冲作用下引爆或引燃的阈值。并采用大口径长程F-P干涉仪和外调制的脉冲激光光源及记录装置,获得了点火药爆轰场和燃烧场的干涉图,并定量计算了燃烧的温度分布。
This peper describes the experimental results of pulsed YAGlaser for igniting detonating powder, for example the threshold of explosionand combustion of detonating powder in action of Q-swicth and free oscillationpulsed YAG laser. At the same time, a large aperture and long path F-P inter-ferometer, modulated pulsed laser and record device are used to obtaine the in-terferograms of explosion and combustion of detonating powder. The tempe-ruture distribution of combustion field is quantitatively calculated by computerfrom the interferogram of combustion.
