Abstract
A pulsed laser diode driver includes an inductor having a first terminal to receive a source voltage, and a second terminal, a source capacitor coupled between the first terminal of the inductor and ground, a bypass capacitor having a first terminal connected to the first terminal of the inductor and a second terminal connected to the second terminal of the inductor, a laser diode having a cathode that is connected to the first terminal of the inductor and an anode that is connected to the second terminal of the inductor, and a bypass switch connected between the second terminal of the inductor and ground. The bypass switch is configured to control a current flow through the inductor to produce a high-current pulse through the laser diode, the high-current pulse corresponding to a peak current of a resonant waveform developed at the anode of the laser diode.
