Design of high-peak current and narrow pulse driver of laser diode

This paper presents a laser diode (LD) pulse driving circuit that can generate current pulses of amplitudes range from 6 to 30A, with pulse widths varying from 5 to 100 ns and frequencies varying from 500 Hz to 50 kHz. It is with monostabillity trigger used as pulse shaping component, with power metal-oxide-semiconductor field effect transistors (MOSFETs) as fast switches and power inverter devices, with low voltage power supply that the circuit generates high-peak pulse current. As its structure is simple and easy to understoand and realize, the circuit is of great value to be used to drive pulsed semiconductor laser.
