In order to satisfy the needs of the rate of fuze pulse front edge, laser pulse width and power in the detection system of laser proximity fuze, by the theory analysis of RLC discharge circuit, double transistors driving high-speed metal-oxide semiconductor field-effect transistor was used as the high-speed switching, and Microprocessor C8051FXXX was adopted to produce pulse trigger signal, a drive power of laser proximity fuze with high-power high-speed and narrow pulse was designed. Through PSPICE software analysis and experimental verification, the drive power can realize that pulse front edge is about 4 ns, pulse width is about 10 ns, and peak current of the laser can reach 50 A. The research effectively improved the ability of system detection range and anti-cloud and dust interference.
