Abstract
A laser marking system and an associated microlaser apparatus are provided which include a submount, a plurality of pump sources operably mounted upon the submount, and a microlaser disposed in alignment with the pump sources such that pump signals emitted by the pump sources pump respective portions of the active gain medium of the microlaser to produce a laser output. In order to impart a mark upon a workpiece that has a number of pixels, the laser marking system can be configured such that each pixel of the resulting mark is produced by the laser output generated by a different portion of the active gain medium of the microlaser in response to pumping by a respective one of the pump sources.
