Abstract:
1. A surface-emission laser array comprising 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 said plurality of surface emission laser diode elements aligned in a second direction perpendicular to said first direction, are formed with generally equal interval in said first direction, said surface-emission laser diode elements aligned in the first direction being disposed with a first interval in said first direction, said surface-emission laser diode elements aligned in the second direction being disposed with a second interval in the second direction, the first interval being smaller than the second interval, 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.
