【Abstract】 Laser initiation has unexampled advantages due to its unique optical initiation mode by contrast with conventional electrical initiation way. In recent years, considerable progress has been made in basic researches and engineering technologies. Moreover, the investigations and applications of laser direct ignition and laser-driven flyer become most attractive highlight in many countries. The application and development of laser initiation technology are summarized. The research actuality of laser direct ignition and laser -driven flyer technology is reviewed. In present, the sizes of laser, the capacity of optical fiber for laser pulses delivery and the reliability of whole laser ignition system restrict the development of laser initiation technology. The four key technologies which should be focused on are the miniaturization of solid laser, the studies on the fiber delivery energy, the optimization of whole optical path and the design of laser detonator. The ways to resolve these problems that block the development of laser initiation technology are proposed. The development and application of laser initiation technology are prospected.更多还原
