Abstract
A driver circuit, for generating narrow electrical pulses of high repetition rate with high peak current and low after pulse ringing to drive an optical load, may include a source, a first circuit path, and a second circuit path. The first circuit path may be connected to the source and may include inductive elements and a switch. The switch being in a closed state may charge current in the inductive elements through the first circuit path. The second circuit path may connect to the optical load and may be connected to the source. The second circuit path may include the inductive elements and a capacitive element in series with the optical load. The switch transitioning from the closed state to an open state may discharge current from the inductive elements through the second circuit path to provide an electrical pulse to the optical load.
