Abstract
Method and apparatus are provided that limit the current ramp rate applied to a laser bar or a single emitter laser diode to a predetermined value of 150 milliamps per millisecond or less. In addition to the laser diode and its power supply, the apparatus includes a power supply control circuit that performs the function of limiting the power supply ramp rate. The power supply control circuit can be separate from, or integrated within, the power supply.
