Shared threshold/undershoot laser output driver

A laser driver apparatus, system, and method include a single laser driver. One or more threshold levels and one or more undershoot levels can be digitally combined into a single output with respect to the single laser driver to reduce the output capacitance of the single laser driver and minimize circuit power, resulting in a faster and higher fidelity signal thereof. A decoder (e.g., thermometer decoding) can also be provided, wherein the threshold level(s) and the undershoot level(s) are thermometer decoded via the decoder.
