Abstract
A multi-laser arrangement, in particular an RGB laser module, having a housing with a housing cap having at least one opening formed therein and a transparent element associated therewith for the passing of electromagnetic radiation. The housing cap coupled to a base plate. A first laser emitting in the red spectral range, a second laser emitting in the green spectral range, and a third laser emitting in the blue spectral range are arranged in the housing. An electrical connection line is routed through the housing to each respective laser. During operation of a laser, a majority of its emitted light passes through the transparent element. Each laser is arranged on a pedestal; spaced apart from the lower surface of the base plate; and is aligned with one another. The main direction of laser emission is substantially parallel to the base plate of the housing.
