Claim 17:
18. A laser device comprising a common waveguide layer, a plurality of laser bodies and a common carrier, wherein
the plurality of laser bodies each comprise an active zone configured to generate coherent electromagnetic radiation,
the plurality of laser bodies are arranged side by side on the common waveguide layer,
the plurality of laser bodies are directly adjacent to the common waveguide layer,
the plurality of laser bodies are phase-coupled to each other via the waveguide layer during operation of the laser device,
the common waveguide layer is located in the vertical direction between the common carrier and the plurality of laser bodies, and
the common waveguide layer comprises a first sublayer, a second sublayer, and an active region arranged therebetween, the active region being located in a coupling path of the waveguide layer.
