Abstract

A laser imager for a printing system, comprising a plurality of independently addressable surface emitting lasers arranged in a linear array on a common substrate chip and including a common cathode and a dedicated control channel associated with an address trace line for each laser of the plurality of independently addressable surface emitting lasers, and optical elements arranged in a linear lens array configured to capture and focus light from the plurality of independently addressable surface emitting lasers onto a imaging member, wherein the plurality of independently addressable surface emitting lasers arranged in a linear array and the optical elements arranged in a linear lens array operate together to image the imaging member.
