RESONANT LASER DRIVER FOR A LIDAR SYSTEM

Abstract:

A pulsed laser diode driver may include at least one low side switching circuit connected to at least one laser diode. The at least one laser diode may generate at least one light pulse. The low side switching circuit may include an input for receiving energy. The low side switching circuit may also include an inductor configured to store at least a portion of the received energy. Further, the low side switching circuit may include a trigger switch. The trigger switch may cause the inductor to store the portion of the received energy when the trigger switch is closed, and the trigger switch may cause the portion of the received energy stored in the inductor to be delivered to the at least one laser diode after the trigger switch is opened.
