The carbon doped BNCP is used as ignition composition, and a laser igniton system, with the func-tion of ignition timing detection, is developed. The working wavelength of the system is 980nm, and the optical pow-er is 0-2W adjustable, and the pulse width is 1-200ms adjustable. A series of laser ignition test has been carried out using the laser igniton system, and the test results show that:the threshold optical power of igniton is 240mW, the minimum total igniton optical power is 400mW, the maximum no igniton optical power is 80mW;and the typical ig-nition time is about 600μs.
