Abstract:
A surface-emission laser array comprises a plurality of surface-emission laser diode elements arranged in the form of a two-dimensional array, wherein a plurality of straight lines drawn perpendicularly to a straight line extending in a first direction from respective centers of the plurality of surface emission laser diode elements aligned in a second direction perpendicular to the first direction, are formed with generally equal interval in the first direction, the plurality of surface-emission laser diode elements are aligned in the first direction with an interval set to a reference value, and wherein the number of the surface-emission laser diode elements aligned in the first direction is smaller than the number of the surface-emission laser diode elements aligned in the second direction.
