The invention relates to a narrow pulse width pulse output circuit comprising a first switching tube and a power supply. The control end of the first switching tube is used for connecting a control signal, and the output end is grounded. The power supply is grounded through a bus capacitor and is also connected with the input end of the first switching tube through a first resistance-inductance load. The input end of the first switching tube is also grounded through a first energy storage unit and a second resistance-inductance load which are series connected. The series connection point of the first energy storage unit and the second resistance-inductance load is used for outputting narrow pulse width pulses. The narrow pulse width pulse output circuit has simple and reliable control andcan realize amplification of the pulse signal power with the pulse width from 200ns to 200mus so as to improve the consistency between the circuit output and the control signal.
