Abstract

A pulse driver based on inductive storage and discharge is developed for driving short 1-5ns current pulses through laser diodes. This driver overcomes the laser diode impedance matching challenge by coil discharge through the laser diode which produces a high compliance 100V open circuit pulse current source. The pulse driver is demonstrated in a laser ranging experiment which employs linear PD amplifier and time gated receiver. The aim of this laser ranging system is immunity to optical interference and capability of ranging through reflecting objects that are not of interest, like water surface or vegetation.
