Classification: CPC H  G | IPC H

Claim 9:
10. A pulsed laser diode 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 a bias voltage node;
a laser diode switch having a drain node that is directly electrically connected to the second terminal of the inductor;
a first laser diode having an anode that is directly electrically connected to a source node of the laser diode switch and a cathode that is directly electrically connected to the bias voltage node;
a bypass switch having a drain node that is directly electrically connected to the source node of the laser diode switch and a source node that is directly electrically connected to the bias voltage node; and
a bypass capacitor having a first terminal that is directly electrically connected to the drain node of the bypass switch;
wherein:
the laser diode switch and the bypass switch are configured to control a current flow through the inductor to produce a high-current pulse through the first laser diode, the high-current pulse corresponding to a peak current of a resonant waveform developed at the anode of the first laser diode.
