Abstract
A method and apparatus to drive a laser diode are disclosed comprising increasing a bias current to the laser diode to a threshold level, wherein the threshold level is below an actuation level of the laser diode and wherein a resistor is placed in parallel to the laser diode, charging a capacitance to a precharge capacitance of a circuit including the laser diode, wherein the precharge capacitance is below a capacitance actuation level of the laser diode; and actuating the laser diode.
