Claim 0:
1. A method for driving an optical load, the method comprising:
charging, by a charging circuit path of an electrical drive circuit, one or more inductive elements,
wherein the electrical drive circuit includes the one or more inductive elements,
wherein a discharging circuit path of the electrical drive circuit includes a first capacitive element in series between the one or more inductive elements and the optical load,
wherein the electrical drive circuit is connected to one or more sources, and
wherein the charging circuit path includes a second capacitive element in parallel with a source of the one or more sources;

generating, by the electrical drive circuit, after the charging, and for a first time interval, a main electrical pulse,
wherein a main current provided by the main electrical pulse is direct-current-coupled (DC-coupled) to the optical load;

discharging, by the discharging circuit path of the electrical drive circuit, after the charging, and for a second time interval, the one or more inductive elements to provide a compensation electrical pulse,
wherein at least a portion of the second time interval overlaps with the first time interval, and
wherein a compensation current provided by the compensation electrical pulse is alternating-current-coupled (AC-coupled) to the optical load;

combining, by the electrical drive circuit, the main electrical pulse and the compensation electrical pulse into a combined electrical pulse; and
providing, by the electrical drive circuit, the combined electrical pulse to the optical load.
