Claim 0:
1. A laser device comprising a common waveguide layer and a plurality of laser bodies, wherein
the laser bodies each comprise an active zone configured to generate coherent electromagnetic radiation,
the laser bodies are arranged side by side on the common waveguide layer,
the laser bodies are directly adjacent to the common waveguide layer,
the laser bodies are phase-coupled to each other via the waveguide layer during operation of the laser device, and
the laser device further comprises a first electrode, a third electrode, and a second electrode disposed between the first electrode and the third electrode, wherein
the first electrode and the third electrode are assigned to a first electrical polarity of the laser device,
the second electrode is assigned to a second electrical polarity different from the first electrical polarity,
the first electrode and the second electrode are configured for electrically contacting the laser bodies, and
the second electrode and the third electrode are configured for electrically contacting the common waveguide layer.
