Patent ID: 6898222

Claim:
A diode laser arrangement comprising: a plurality of diode laser arrays, each diode laser array being connected with a thermal contact surface of a heat-spreading carrier and containing a p-n junction plane parallel to the thermal contact surface; said heat spreading carriers arranged adjacent to one another, said diode laser arrays forming a radiation source with a line shaped laser beam bundle profile and fastened to a cooling surface of a common cooling element wherein each heat spreading carrier is electrically insulated from the cooling element; the cooling surface extending parallel to the thermal contact surfaces; said diode laser arrays being fastened to the thermal contact surfaces of said heat spreading carriers so as to be separated from one another and said diode laser arrays being electrically connected in series; every heat spreading carrier being constructed as an electric anode contact to the connected diode laser array and having a cathode contact which is connected to the heat spreading carrier and which is electrically insulated from the heat spreading carrier; and wherein each of the cathode contacts being electrically connected to an adjacent heat spreading carrier in a series connection.
