摘要： A semiconductor surface-emitting laser array can be provided with a group of independently addressable light-emitting pixels arranged in at least two rows and in a linear array on a common substrate chip and including a common cathode and a dedicated channel associated with an address trace line for each pixel. An aggregate linear pitch can be achieved between pixels of the at least two rows along the linear array in a cross process direction that is less than the size of a pixel. The semiconductor laser array can include more than one common substrate chip tiled and stitched together in a staggered arrangement to provide an at least 11-inch wide, 1200pdi imager with timing delays associated with each of the more than one common substrate chip in the staggered arrangement.

摘要： 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.
