ABSTRACTLaser initiation of energetic materials has been an interesting and promising research area due to its safety and reliability features and its great potential for initiation device miniaturisation. This article has critically reviewed its research in terms of the effects of essential initiation parameters, including laser wavelength, optical absorption and laser power on its performance. It aims to show the research and development of laser ignition initiation applications, in particular explosive devices. In addition, this article may also give guidance and recommendations for future research and development in laser initiation applications to energetic materials.
