摘要:设计了一种使用半导体激光点火的火工品系统，该系统以BNCP起爆药或B/KNO3点火药作为激光火工品药剂，采用直接点火的方式。通过对其点火延迟时间和点火能量的研究，最终确定了药剂的装药量及装药密度，实现了整个系统的低能可靠发火。同时对药剂进行了射频试验，结果表明当磁感应强度为2T时，不会影响药剂的发火性能。
Abstract:An initiating system ignited by semiconductor laser was designed. The system adopted direct ignition method, which use BNCP primary explosive or B/KNO3 ignition powder as laser initiating explosive. Through the study of ignition delay time and ignition energy, the charge mass and charge density were determined finally，so that the low energy and reliable ignition of the whole system was realized. At the same time, the radio frequency test of the charge showed that when the magnetic induction intensity is 2T, the ignition performance of the charge will not be affected.
