PROBLEM TO BE SOLVED: To provide a semiconductor laser array capable of making an NFP (Near Field Pattern) in a uniform shape without dropping energy conversion efficiency. SOLUTION: A plurality of striped ridges 11A arranged side by side are assembled and grouped at a plurality of positions. A light emitting group G1 consists of four ridges 11A, and a light emitting group G2 consists of three ridges 11A. The respective groups G1 and G2 are placed at equal pitches so that their center positions are cyclic. A width W2 of a gap between the respective groups G1 and G2 is wider than widths W1 and W3 of the respective groups G1 and G2. The plurality of ridges 11A in the respective groups G1 and G2 are placed at equal intervals wider than a stripe width of the ridge 11A. COPYRIGHT: (C)2008,JPO&INPIT
