Abstract
A semiconductor laser light source comprising an edge-emitting semiconductor body () is provided. The semiconductor body () contains a semiconductor layer stack () having an n-type layer (), an active layer () and a p-type layer () which is formed for generating electromagnetic radiation which comprises a coherent portion (). The semiconductor laser light source is formed for decoupling the coherent portion () of the electromagnetic radiation from a decoupling surface () of the semiconductor body () which is inclined with respect to the active layer (). The semiconductor body () comprises a further external surface (A,B,C) which is inclined with respect to the decoupling surface () and has at least one light-diffusing sub-region (A,B,C,A,B) which is provided in order to direct a portion of the electromagnetic radiation generated by the semiconductor layer stack () in the direction towards the further external surface (A,B,C).
