1. A laser projection arrangement, comprising:
a sub-mount carrier with a main surface;
at least one edge-emitting laser arranged on the main surface, whereas the at least one edge-emitting laser is facing the sub-mount carrier and comprises at least one laser facet that is positioned at a predefined distance from the main surface; and
a planar light circuit with at least one light guide having an inlet, wherein the planar light circuit is arranged on the main surface such that the at least one light guide and the inlet is facing the at least one laser facet and is positioned at the predefined distance from the main surface of the sub-mount; and wherein
the at least one edge-emitting laser comprises at least two ridged resonators substantially parallel to each other and spaced apart by a distance in the range of 10 μm to 100 μm.
