ABSTRACT:
A plurality of lasers (having openings 170) are formed at predetermined positions at equal intervals on at least two main scanning lines on a semiconductor substrate 100. The lasers have each a predetermined beam diameter and take different positions in the main scanning direction, thereby providing a two-dimensional surface emitting laser array emitting laser beams through a lens system to form a pixel line with no gap on the main scanning line of an image formation face moving in the sub-scanning direction. The two-dimensional surface emission laser array is used to provide a laser beam scanner, a laser beam recorder, and a laser beam recording method.
