Abstract

L'invention concerne une source de lumière laser (100) comprenant une pluralité d'émetteurs (200, 200a, 200b,..) à émission surfacique disposés sur un élément support (300), caractérisée en ce que différents émetteurs (200a, 200b) à émission surfacique sont respectivement conçus et/ou disposés les uns par rapport aux autres sur l'élément support (300), de façon que les directions principales (H1, H2) du rayonnement laser qu'ils émettent ne sont pas mutuellement parallèles, et/ou en ce qu'une densité d'assemblage qui décrit une distance entre un premier émetteur (200c) à émission surfacique et au moins un émetteur (200d) à émission surfacique adjacent dans au moins une dimension, n'est pas constante.
