Pulsed resonant laser diode array driver

A pulsed laser diode array driver comprising:

• an inductor having a first terminal and a second terminal, the first terminal being configured to receive a source voltage;
• a source capacitor having a first capacitor terminal directly electrically connected to the first terminal of the inductor to provide the source voltage and a second capacitor terminal electrically coupled to ground;
• a bypass capacitor having a first terminal that is directly electrically connected to the second terminal of the inductor and a second terminal directly electrically connected to ground;
• a bypass switch having a first node that is directly electrically connected to the second terminal of the inductor and a second node that is directly electrically connected to ground;
• a common-anode laser diode array comprising one or more rows, each row comprising a plurality of laser diodes, respective anodes of all of the laser diodes being connected in common to a single common-anode node, and respective cathodes of each of the laser diodes of each row of the one or more rows being connected in common to a respective row cathode node;
• and
• one or more laser diode switches, each laser diode switch having a respective first node directly electrically connected to a respective row cathode node and a respective second node directly connected to ground;
• wherein, the one or more laser diode switches and the bypass switch are configured to control a current flow through the inductor to produce respective high-current pulses through each row of the common-anode laser diode array, each of the high-current pulses corresponding to a peak current of a resonant waveform developed at that row of the common-anode laser diode array.
