A laser diode is employed to output light. A laser driver is employed to drive the laser diode. A laser driver control unit is employed to control the driving, such that carrier concentration of the laser is substantially forced to a desired concentration as photon level of the laser initially arrives at a desired level. In one embodiment, the laser driver outputs a drive pulse to drive the laser diode, with the drive pulse having a complex waveform. In one embodiment, the complex waveform includes different transition time periods, and transient rates to raise the drive pulse from an initial level to a peak level. In another embodiment, the complex waveform includes different transition time periods and transient rates to raise the drive pulse from an initial level to a transition peak level and then drop the drive pulse back to an intermediate low level and then finally transition to a final peak level.
