1. A pulsed laser diode array driver, comprising:
a bypass switch having a first node that is configured to be directly electrically connected to i) a single common node of a laser diode array, ii) a first node of a bypass capacitor, and iii) a first terminal of an inductor, wherein a second node of the bypass switch is configured to be directly electrically connected to ground; and
a first laser diode switch having a first node that is configured to be directly electrically connected to a first row of the laser diode array and a second node that is configured to be directly electrically connected to ground;
wherein:
the first row of the laser diode array comprises a first plurality of laser diodes;
a first node of each respective laser diode of the laser diode array is electrically connected in common to the single common node, and a second node of each respective laser diode of each row of the laser diode array is electrically connected in common to a respective row node of the laser diode array; and
the first laser diode switch and the bypass switch are configured to control a current flow through the inductor, developed using a source voltage received at a second terminal of the inductor, to produce a first high-current pulse through the first row of the laser diode array, the first high-current pulse corresponding to a peak current of a resonant waveform developed at the first row of the laser diode array.
