This paper describes the design of laser ignition system for fighter escape ejection system. The system adopts metal, integrated high power fiber coupled laser modules as the igniting light source, with fiber core diameter 105μ m and optical output power 0-5W adjustable. The laser driving circuit is based on solid relay. The laser ignition system uses embedded microprocessor to control multiple laser detonator, and can accurately achieve relief, throwing cover, seats ejection in at most three locations. The ignition system adopts dual redundant methods to improve ignition reliability, and has such advantages as precise timing control, high reliability, easier to implement complex logic and so on comparing with the traditional way of detonating cord.
