Abstract:
A two-dimensional surface emitting laser array comprising:a substrate;a first laser array having a plurality of lasers placed in a first spacing along a base line on said substrate; andat least a second laser array having a plurality of lasers placed along a plurality of inclined lines, each laser crossing the base line at a predetermined angle on the substrate,the lasers of said first laser array and the lasers of at least said second laser array being placed so as to form an array of pixels equally spaced from each other and with no gap in the direction of the base line,the inclined lines including a first inclined line having a first angle as the predetermined angle and a second inclined line having a second angle different from the first angle, andthe lasers of at least the second laser array being placed along the first inclined line and the second inclined line.
