Abstract

Die Erfindung betrifft eine Laserlichtquelle (100) mit einer Mehrzahl von auf einem Trägerelement (300) angeordneten Oberflächenemittern (200, 200a, 200b,..), dadurch gekennzeichnet, dass unterschiedliche Oberflächenemitter (200a, 200b) jeweils so ausgebildet und/oder relativ zueinander auf dem Trägerelement (300) angeordnet sind, dass Hauptstrahlrichtungen (H1, H2) der von ihnen emittierten Laserstrahlung nicht parallel zueinander sind, und/oder dass eine Packungsdichte, die einen Abstand eines ersten Oberflächenemitters (200c) zu mindestens einem hierzu benachbarten Oberflächenemitter (200d) in mindestens einer Dimension beschreibt, nicht konstant ist.
