This application describes a laser driver that can include a voltage source, an inductor, at least one capacitor, a diode laser, and an electronic switch. The switch may be connected to ground and may be configured to alternate between an on state and an off state. In a first on state, current may flow through the switch to the inductor and through the inductor to store energy in the inductor. In a first off state, the inductor may release the stored energy and allow current to flow to the at least one capacitor to charge the at least one capacitor. In a second on state, the at least one capacitor may discharge and allow current to flow through the diode laser to cause the diode laser to emit light energy.
